Slot Allocation At LHR For Summer 2008  
User currently offlineVV701 From United Kingdom, joined Aug 2005, 7399 posts, RR: 17

According to ACL who are responsible for allocating and monitoring the use of slots at LHR and other UK airports, their starting point for the allocation of slots at LHR for the upcoming summer timetables was the summer 2007 baseline of 9,489 allocated weekly air transport movements.

Of these 9,489, 33 were confiscated due to use-it-or-lose-it failures (although I suspect this includes slots given up when services were discontinued and the timings meant they were not in high demand by others).

A further 4 slots were not reclaimed when the applications for Summer 2008 slots were received.

There was a 10 slot gain described as 'Fill in periods' which I assume are new slots squeezed out of the system but here I welcome correction.

Finally 9,462 were claimed by grandfather rights or, as ACL prefers, 'Historics'.

The weekly capacity for Summer 2008 between 0500 and 2155 UTC is given as 9,562 slots. Of these 9,516 were used in the slot allocation process resulting in 46 slots or 1.6% remaining unused presumably because no airline wanted them.

A total of 87 airlines claimed the 9,462 'Historics'. The 'top ten' of these were:

BA 3,930
BD 1,066
LH 406
VS 322
EI 302
SK 276
AA 236
IB 210
AC 196
KL 196

Of these 87 airlines 33 applied for additional slots for the summer 2008 timetable. There applications totaled 525 slots. Additionally 11 airlines with no 'Historics' applied for a total of 915 slots.

The weekly capacity for Summer 2008 between 0500 and 2155 UTC is given as 9,562 slots. Of these 9,516 were used in the slot allocation process resulting in 46 slots or 1.6% remaining unused presumably because no airline wanted them.

So with 9,516 slots allocated and 9,462 claimed as 'Historics' there were not many 'new' slots available to meet the demand for new slots of 1,440 (525 + 915).

The list of new applicants is interesting. They were (with the number of slots applied for):

5W (Astraeus Airlines) 56
8A (Atlas Blue) 6
CO (Continental Airlines) 56
DL (Delta Airlines) 42
E0 (Eos) 26
IT (Kingfisher Airlines) 28
NW (Northwest Airlines) 42
SW (Air Namibia) 6
US (US Airways) 84
W3 (Arik Air) 28
Z4 (Zoom Airlines Inc) 14

One interesting aspect of the list is the number of slots that each of the new-to-LHR American airlines applied for. Another is the presence of Eos and Zoom Canada on the list. But unfortunately none of the above were allocated a single slot. (With the US airlines I suspect that the arrangements they were making with their partner airlines played a significant role in this. Here it should be recognised that a slot application requires the applicant to state the destination and the type of aircraft to be used.)

So who was the big winner? It was RG who applied for and were allocated 14 slots for a daily service. This is a little ironic as they have, I understand, since decided to discontinue the service they have been operating since the start of the Winter 2007-08 Schedules. The next biggest winners were BA and BD. BA applied for 66 new slots and were awarded 6, confirming the award of 2 new slots for the current winter schedules and 4 for new services starting this summer. BD applied for 28 and also received 6, 2 already being used and 4 totally new. Four slots were awarded to AI, B3, EY, and VS and 2 to 9W, MU,SK, SU and VK. One (!) was awarded to each of AF and KL which in theory should mean that all their aircraft should be parked at LHR by the end of the Summer Schedules. But I guess that somehow these two allocations are linked.

The net result of the above, inter-airline slot exchanges and reallocation of 'Historic' slots within an airline is that the largest changes in Air Transport Movements per week by country in Summer 2008 compared with Summer 2007 will be as follows:

USA: From1082 to 1296 (+19.8%)
Russia: From 130 to 146 (+12.3%)
India: From 218 to 238 (+9.2%)

Italy: From 404 to 360 (-10.9%)
Ireland: From 398 to 342 (-14.1%)
France: From 452 to 388 (-14.2%)

The largest route out of LHR is that to JFK. 2,751,835 passengers flew this route in 2006. A total of 17 routes had more than 1 million passengers. They were:

1. JFK 2,751,835
2. DUB 1,990,817
3. CDG 1,970,532
4. AMS 1,896, 171
5. ORD 1,520,976
6. FRA 1,513,118
7. EDI 1,495,042
8. LAX 1,430,025
9. HKG 1,416,789
10. DXB 1,374,451
11. GLA 1,284,458
12. MAD 1,120,572
13. SFO 1,077,884
14. SIN 1,066,322
15. YYZ 1,025,536
16. IAD 1,040,222
17. BOM 1,005,852

The change in available seats by country in Summer 2008 compared with last year broadly reflects the change in ATMs of which the highlights are given above. So the USA will show a growth of 20.8% to 297,790 seats a week followed by India with a growth of 11.2% to 66,718 seats per week. The biggest decline is to Ireland at -10.2% to 66,452 seats per week. The fall in seat numbers to France with the transfer of slots from AF's CDG-LHR service to its partner airlines, primarilly DL, is lower in percentage terms at -9.1% as larger aircraft will be used on the remaining LHR-CDG flights. However as the historic decline in passengers on this route has been typically around 2% per annum under the impact of LCCs and the Channel Tunnel (from, for example, 2,010,765 in 2005 to 1,970,532 in 2006) it looks as if load factors may raise substantially on this route this summer.

All the above data has been derived from reports issued by Airport Coordination Ltd and the Civil Aviation Authority.

That's how the system is 'designed' to work - it favours those already established at the airport. In fact you could say that statistically BA & BD were penalised by getting the tiniest %age of what they already have & asked for as an increase.

I believe that the European Union has determined the broad principles of slot allocation which are applied to all of Europe's major airports, so it's not an LHR peculiarity.

Of course intercontinental network hubs like DXB, SIN & HKG are going to be very high on the list of available seats flown, even though in terms of final destination they should be much further down the list. That's also why Sydney is usually listed here in the UK as one of the favourite longhaul destinations, yet does not feature at all in the above statistics because there is as yet no direct non-stop service.

The figures are by destination. The number of passengers flying between SYD and LHR via BKK, HKG and SIN in 2006 was 795,929. The only passengers who might be excluded from this number are, I believe, those who broke their journey. But it is not clear to me whether they are also in the figures published by the CAA if their flights were booked at a single ticketing.

The first point to note is that all three of the British airlines based at LHR were awarded new slots. In addition to BA's and BD's 6 slots (3 slot pairs a week) VS asked for and got 4 slots (although these were already in use starting with this winter's schedules). But with these airlines being awarded 16 of the available 54, overseas airlines strengthened their position at LHR compared to the British residents. The percentage of LHR slots operated by British airlines will therefore fall very slightly from 56.2% in the Summer 2007 schedules to 56.1% in the summer 2008 schedules.

I think it is unlikely that there is any other significant airport in the world where domestic airlines have such a small share of all slots. Indeed if you consider that of the 67,339,000 passengers at LHR in 2006 as many as 5,993,000 or almost 9% were UK domestic passengers you will see that overseas airlines already carry more international passengers at LHR than do British airlines. So there is an argument that the British airline share of slots should be growing, not declining.

By the way in view of your probable personal interests, 9W had 54 slots, asked for 2 more and were allocated both of them. AI had 70 slots, asked for 10 more and were allocated 4.

Correct typo

VV701, thanks for the interesting information/analysis.

Question: of all of those new-entrant U.S. airlines you mentioned that applied for new slots (CO, DL, etc.), did any of them receive new slots directly from ACL, or did all of their new slots (4 daily departures each, for example, in the case of CO and DL) come from exchanges with other airlines?

Ah, ok. Of course one should really add DXB into that equation, which could push it up quite a bit.

Actually you raise quite a big question about how those numbers are collated by CAA - how would they know who is & who is not breaking their journey to Australia? The only way I can think that might be quantifiable is by the destination that pax are checked through to, regardless of the route, which CAA could probably gather from airport/airline checkin data. But then one would expect CDG, AMS & FRA to be much lower on the list given that they are also very busy transfer hubs ex LHR, and are therefore not the final destination of a very large proportion of the pax travelling...

* RG was first allocated its 14 slots for the Winter 2007-08 timetable
** VK was the only airline without slots in the Winter 2007-08 timetable to be awarded slots for the Summer 2008 timetable.

Note that an important factor is the time and the day that the slot request is for. A pool of 54 offered slots remains available because they could not be matched to any applicants needs. 98% (all but one) of the newly allocated slots were for timings within 120 minutes of the applicants request.

Overall 60% of all 9,462 slots allocated were for the time requested, 76% within plus or minus 5 minutes and 92 per cent within plus or minus 30 minutes.

I think historically, a lot of them have been late evening, which isn't a particularly attractive time to arrive (unless you're returning to UK from Europe).

Landing slots or Airport slots are rights allocated to an entity by an airport or government agency granting the slot owner the right to schedule a landing or departure during a specific time period. Landing slots at some major airports are controlled by grandfather rights for airlines that were in place when these restrictions were added, for example: British Airways at Heathrow Airport.

You are not stupid! On a-net there are often strong trans-Atlantic disagreements. One of the reasons is that we Europeans think that what happens over there must be the same as what happens over here while you Americans think that what happens over here must mirror what happens over there. And very often what actually happens on the two sides of the North Atlantic is very different. 'Slots' is one example.

Over there - correct me if I am wrong - every airline could theoretically time an arrival at a specific airport at the same time. What controls whether or not it can actually operate to the stated arrival time is whether or not it has a gate to park an aircraft at and disembark its passengers once it is on the ground. So ownership of a gate is everything. And each gate is owned or leased by a specific airline.

To take a totally ridiculous example, this means you could have an airline that had 5 gates at airport A out of a total of, say, 50. At a specific time on a specific day that airline could have five flights to be scheduled at a gate but no other airline's aircraft were scheduled to be at that airport. But although there were 45 unused gates, until the first airline has negotiated to lease a sixth gate at that time that airport is effectively slot bound to that airline.

Over here gates are not assigned or controlled by the airlines. They are owned by the airport operator who is usually a commercial or semi-commercial company such as BAA who own LHR and LGW and are a subsidiary of a Spanish owned construction company. This is unlike the USA where most major airports are owned and operated by a local or community authority such as the New York Port Authority who own JFK. Over here if a BA aircraft lands at LHR the chances are that it will be directed to a gate owned by BAA and usually used by BA. But it may be directed to a gate never previously used by BA. And, to handle the passengers, BA ground handling staff will have been moved to that gate to greet the passengers.

Of course nothing is as simple as it is meant to be. At LHR our understanding of a slot is that it is an arrangement for runway space at a given time on a given day for the aircraft to take off or land. But as well as having a finite runway capacity LHR has a finite terminal capacity (measured by number of arriving or departing passengers) and a finite number of stands. To ensure 'fair use' of slots allocated by ACL that company also monitors the use of those slots. So if an airline's aircraft consistently misses its allocated slot it will get a warning and if it continues to miss it will have the slot confiscated.

Because no system is ideal the LHR Summer 2008 has required schedule adjustments that are dependent not only on runway slots but also terminal capacity and stand availability. However allocation is initially made on the basis of runway slots. Of the 9,516 allocated slots, 8,504 (89.4%) required no adjustment following this initial allocation. 890 allocated slots (9.3%) had to have a schedule adjustment because of actual forecast runway availability. 84 allocated slots (0.9%) had to be adjusted because of the restrictions of terminal capacity. Just 7 allocated slots (0.1%) required adjustment because of stand availability limits. A further 31 (0.3%) required adjustment because arrival and departure timings were closer than the minimum ground time required to turn the aircraft round. (Source for the data in this paragraph: ACL.)

Now if such data were available for any American airport I believe that the stand availability limits would be the major variable. However in the USA if my understanding is correct except in rare examples like the FAA's recent intervention at overcrowded JFK, there is no such overall coordination. So similar information for the upcoming summer schedules will not be available.

So what does this mean in practical terms? If an aircraft departure from a gate at a UK airport occurs late, perhaps because a checked in passenger has gone shopping, there is a danger of the aircraft missing its departure slot. It may therefore now face a significant delay until it can be allocated another slot that will not significantly delay the departure of other 'on time' aircraft. It also means that there can be a queue of several aircraft waiting to take off at the end of the runway and another aircraft arrives and because it is still on time it passes the other aircraft and goes straight to the front of the queue. Under similart circumstances at a US airport I believe it would just join the back of the queue. It is my understanding that 'over there' aircraft depart not in slot order but in the order they arrive on the taxiways to the end of the runway.

30 KYNG2KPBI : Thank you for such an excellent explanation of slots, I learned a lot out of that post.
31 AS777 : YES!!! Thank you VV701. I am pretty sure I understand now. But I do have another question. Are slots transferable? Example.....A flight leaves JFK 2
32 Rivet42 : It doesn't work like that in real-time. Whilst slots have a nominal time 'window', that is only so that you don't have all the airlines trying (or wa

34 AirNZ : As superb an a/c as a 777 is, it is neither the Holy Grail or the be-all/end-all of aviation though.
35 AS777 : Thanks guys! I have learned a lot today, and now I can understand what you all are talking about when it comes to "slots"! Have a great weekend
36 LipeGIG : Ironic and pathetic. They applied for and got the "Gold" medal of the aviation and are not able and smart enough to innovate. They could use the slot
37 Jfk777 : US Airways is the last airline I worry about going to LHR. How many people traveled from PHL to London?
38 MasseyBrown : Using July and December for averaging, PHL-London traffic is about 33,000 pax a month. Jan and Feb are the lowest months, so a true average is probab
39 FlyASAGuy2005 : Aren't all gates on E in ATL common use?

41 Humberside : These are charters. bmi dont sell any seats on these flights, indeed the tour operators are often smaller ones that may not even do flight only
42 LHR27C : VV701 - this is not quite correct. At LHR, at least when I was on work experience a couple of years ago, all gates at T1 and T4 are actually assigned
