Flight Numbers

Thu Jun 13, 2019 10:50 pm

How are flight numbers typically assigned? I know that single digit numbers are for most lucrative routes between major cities (NYC-Paris, etc) whereas 4 digit ones are for regional and short-haul.

It varies airline to airline

Emirates for instance have different blocks for different geographical regions.

I'm not 100% sure but it goes something like

EK1-199 Europe
EK200-299 North and South America
EK300-399 Asia
EK400-499 Australasia
EK500-599 India
EK600-699 Non India Subcontinent ?
EK700-799 Africa
EK800+ Middle East

DL, for a time, had 200 series flights which departed from JFK's Terminal 2 and 400 flights leaving Terminal 4, but I think they abandoned that practice.

UA's TPAC flights used to be 800s and TATL 900s.

US, in their last few years of existence, had TATL in the 700 range. I couldn't help but notice their two flights to Brazil were 800s.

Occasionally, airlines will also have fun with numbers to make a local or topical reference. CMH has had many 1492s over the years, IND the same with flight 500, PHL with 1776, etc.

Do you now? That rather implies you don't think an airline such as Lufthansa operate lucrative routes. The fact of the matter is there's no common logic to how flight numbers are assigned between different airlines. Some will do it this way, some the other and others again will find a third way. Lufthansa's US services are in the 400 range; all of SK's long haul routes are in the 900 range regardless of destination; a few of BA's US services are single, but most of them are actually 3 digits, with the balance of the single digits going to Asia/Oceania. Oh, and some of the longest and most lucrative freighter services operate on 4-digit flight numbers.

Rhyme or reason? Better look for it elsewhere :)

For Qantas, QF 001 to 399 is for international flights. QF 400 and above is for domestic ones.

Most airlines will assign single-digit numbers, especially 1 and 2, to flights that are important from a marketing or strategic perspective. BA LCY-JFK, DL JFK-LHR, SQ SIN-HKG-SFO, QF SYD-SIN-LHR (no doubt to be transferred to SYD-LHR with Project Sunrise), AA A321T service JFK-LAX, AS ANC-SEA-DCA, etc., etc.

Large airlines with regional affiliates will tend to use higher four-digit numbers for regional flights.

Beyond those two themes there is vanishingly little consistency.

More specifically:

QF1-199 are Qantas operated international flights
QF200-399 are intenrational codeshares departing from Australia, not including EK flights
QF400-1399 are domestic mainline
QF14xx are SYD-CBR and SYD-WTB Dash 8 services
QF1500-1999 are 717 services
QF2000-2599 are Dash 8 services, not including SYD-CBR/WTB
QF2600-2999 are Fokker 100 services

Within this there are patterns, most notably QF4xx is SYD-MEL/MEL-SYD and QF5xx is SYD-BNE/BNE-SYD

All EK codeshares are QF8xxx, where xxx is the EK flight number. Thus EK1 is QF8001 and EK434 is QF8434.

Slightly off topic, but I never understood BA's system for assigning outbound flights a higher number than inbound flights. For instance, LHR-KWI is BA157, whereas KWI-LHR is BA156! Anyone knows why?

Both FI and NY have a clear system in place, although it has changed slightly with more N-American flights at FI in recent years.

FI:
2XX - Denmark
3XX - rest of Scandinavia (Norway, Sweden, Finland)
4XX - UK / Ireland
5XX - European mainland (Netherlands, Germany, Switzerland, France, Belgium)
6XX - N-American routes added prior to 2014
7XX - Icelandair Cargo
8XX - N-American routes added after 2014
14XX - around the world charter flights
15XX - charter flights from Iceland (not sure if these last two always apply)

NY:
XX - IFJ
1XX - AEY
2XX - Greenland
3XX - EGS
4XX - used to be VEY
5XX - flights operated by Norlandair
6XX - charters

5XXX on both used to be Icelandair flights operated by NY (KEF-ABZ/BHD) that briefly operated from 2016 to 2018.

It’s not higher numbers, it’s odds are outbound, evens inbound.

B6 sometimes has the same last digits for all flights on the same route. For example JFK-BTV has 34, 234, 1634 and JFK-ROC has 286, 486 and 586. Some of the BOS-DCA flights are -89. BTV and ROC have been around a long time. I don't believe this is often or ever done on new routes or added flights.

It seems certain airlines assign even numbers to a particular direction (IE eastbound) and odd numbers the opposite.

Like other said, it varies between airlines.

For example, for CX:
0-99: CX Cargo
100-199: Australia/NZ
200-299: Europe
300-399: Europe, Mainland China (PEK, PVG)
400-499: Taiwan, S. Korea (450/451 continues to NRT via TPE)
500-599: Japan (530/531, 564/565 both stops at TPE)
600-799: SE Asia (Except Philippines), South Asia (India, Maldives, Sri Lanka), Middle East, South Africa (700s)
800-899: US/Canada
900-999: Philippines

4-digit are used for codeshares (i.e. CX5xxx are all KA flights), Charters (8xxx), and one-time flights (2xxx, i.e. ferry flights)

For KA:
100-199: South Asia (India/Bangladesh/Nepal)
200-299: SE Asia (Except Malaysia, Philippines, Indonesia)
300-399: Philippines, Indonesia, South Korea, Japan
400-499: Taiwan
500-599: Not Used
600-999: Mainland China, Malaysia (PEN = 600s, KUL = 700s).

For mainland China domestic flights, Flight Numbers are assigned according to geographical region across all airlines IIRC, i.e. 1xxx = Beijing (North), 2xxx = Xi'an (Not sure), 3xxx = Guangzhou, 4xxx = Chengdu, 5xxx = Shanghai, 6xxx = Chongqing (Again, not sure); dated from CAAC date. All domestic flights (with the exception of "one-stop" flights to long-haul destination, for example, CZ659 is run CAN-WUH-SFO) are 4-digits. It used to be the case that the 2nd digit represent where the flight will fly to, i.e. 15xx = Flights from Beijing (North) to Shanghai (East) on a plane based out of Beijing (i.e. CA), while 51xx = Flights from Shanghai (East) to Beijing (North) on a plane based out of Shanghai (i.e. MU), but I think that's drop as they're running out of flight numbers.

Even now, you see 1xxx and 4xxx (and 8xxx) being used mainly by CA (Along with HO, SC, ZH, etc.); 2xxx and 5xxx (and 9xxx) being used mainly by MU (and FM), and 3xxx and 6xxx (and 8xxx) being used mainly by CZ (and MF). HU mainly use 7xxx for domestic flights, and 9C (Spring Airlines) use 8xxx mainly (there's a few flights with flight number in 6000s range).

Then you got WN (Southwest), which is all over the place for flight number with the exception of 1-99 (Something like that), which always has a DAL-HOU (or v.v.) leg.

It depends...

Using CX:
To East Asia (Including Mainland China) and North America (Both "East" of HKG): Even Outbound, Odd Inbound
To Europe, South Africa, Middle East, SE Asia, South Asia (All of which are "West" of HKG, even though flights to/from Europe technically fly north) along with AusNZ: Odd Outbound, Even Inbound.

For JL, all domestic flights out of HND/NRT are Odd Number regardless of direction, as is all domestic flights out of ITM/KIX and NGO/NKM, except for flights to/from Tokyo (where Tokyo's numbering system "takes precedence"). I believe they then go from South to North (except OKA) in terms of precedence, at least for the "major" airport, i.e. flights out of FUK are all odd number except to/from Tokyo/Osaka/Nagoya; then Hiroshima, Niigata, Sendai, and eventually Sapporo. Thus CTS->KIJ is Even but CTS->AXT is Odd. OKA is somewhat oddball as JTA (Subsidiary of JAL) use Even number for all flights to (i.e. Outbound) to Mainland Japan, but Odd Number for outbound flights to places like ISG and MMY.

JL's International Flights doesn't follow the "Inbound/Outbound" pattern, though, but rather it's similar to CX - i.e. Even Outbound, Odd Inbound for flights to/from North America and Hawaii, but Odd Outbound/Even Inbound for everything else (Including Australia and Guam).

It's kind of both. They could have used 155 for the outbound and 156 for the inbound. Doing in the way they have is still "odd" I guess, although not on my worry list.

From just looking at CDG, it seems like for non-Domestic intra-European flights, along with flights to/from Algeria, Tunisia, and Morocco, they keep (for the most part) the same two number at the end, i.e. CDG-FCO are all in xx04 (Outbound)/xx05 (Inbound), CDG-MXP are all in xx30 (Outbound)/xx31 (Inbound), etc. They don't seems to keep a incremental pattern base on time, though, i.e. For CDG-FCO it's 1204-1504-1104-1304-1604-1404-1004 from Morning to Evening.

Domestic Flights seems to follow an incremental pattern base on time out of both CDG and ORY, usually 6000s or 7000s.

Also, it seems like, for the most part, AF keeps all their Outbound (from Paris) flights Even number, and Inbound flights Odd number. Skimming through the departures from CDG, I only saw two exception (AF775, which is CDG-BGF-NSI-CDG; and AF741, which is CDG-PUJ-SDQ-CDG). That can be explained base on the fact that those two are both triangular flights.

Most still are, but not all of them. All of the TPAC flights from EWR and IAH are not 8xx flights (since they were inherited from CO), and some of the newer ones from SFO aren’t as well. A couple examples from SFO being SIN (UA 1/2 and UA 28/29), CTU (UA 8/9), and KIX (UA 34/35).

Eastern Airlines flights were organized as such...
*Northbound flights ended in even numbers while Southbound odd.
*1-99 were LAX flights as well as NYC to MIA
*100-199 were flights that originated in Northeast cities and terminated In Florida cities
*200-399/500-799 were random domestic or Canada services
*400-499 were flights that departed between 9pm and 5:59am
*800-899 were flights that terminated/originated in Bahamas/Bermuda
*900-999 were flights which originated/terminated In Caribbean/Latin/international cities
*EA-AS followed by the departure time were air shuttle operations
*1000-1999 were extra sections
*2000-5000 were Express affiliate flights
*9000 series were ferry/positioning/charter ops

Cathay also uses 800+ for their NA flights.


Most still are, but not all of them. All of the TPAC flights from EWR and IAH are not 8xx flights (since they were inherited from CO), and some of the newer ones from SFO aren’t as well. A couple examples from SFO being SIN (UA 1/2 and UA 28/29), CTU (UA 8/9), and KIX (UA 34/35).


Gotcha, thanks

7200-8999 AC Express carriers

Air Canada's flight to GRU (Brazil) is AC-090 being the return AC091

LIM is AC80/81 as well, I guess the higher series of the 0-99 range are Latin American flights.

And Air Canada 033/034 is YYZ-YVR-SYD and back.

Fun fact: UA34/35 was actually former UA885/886. Why they renumbered it, I have no idea.

A number of airlines have had the practice for many years of assigning east travelling flights to even numbers and west travelling flights to odd numbers; similar for northbound (even) and southbound (odd). I note that in recent years many have departed from this convention yet it remains predominant as far as I can work out. Not sure where this convention comes from. Would be curious to know.

Porter actually do the complete opposite of convention.

I wonder if any airlines have routes that have both even and odd numbers in the same direction?

Maybe the even-odd numbering convention originated from the railways?

Interesting flight numbers from Hainan Airlines:

HU 496 from SEA to PEK
HU 7956 from SEA to PVG

Why such big differences?

If it helps BA has even numbers for outbound short haul and odd numbers for long haul outbound

There are broad regional sub numbering although a shortage of numbers means this is not wholly applicable

Northwest used to do this, with some exceptions. And there were a few blocks that were dedicated to certain business markets to make them predictable for frequent flyers. The advent and proliferation of alliances and codesharing really put a massive strain on flight numbering, since there must be a unique flight number attached to it, whether it's a marketing or operating flight. And those ranges are dynamic, fluctuating quite a bit as some flights come and go, and a partner mix of what cities you code on changes.

Plus, you have dedicated--albeit smaller--ranges strictly dedicated to maintenance ferry flights, charters, emergency response, etc. The list is quite dizzying for most major airlines.

Then there's the novelty flight numbers that US carriers have done.... Flight 1492 CMH, 500 IND, 1776 PHL, and so on....

Odd numbers for north / west and even numbers for south / east is an IATA convention.

It seems like aircraft switch bases very regularly, so this is all quite fluid! Also, this took me far too long. I need a life!

It was always my (unofficial) opinion that after the merger with Canadian Airlines, Air Canada used double digit flight numbers for routes that didn't quite "fit in" with the way Air Canada did things. So Asia (AC's routes renumbered), South America and the South Pacific all got double digits plus the existing CP single digits.

It sure beats the "old way" when Air Canada numbered flight numbers by aircraft type. 100-399 Viscount, 401-599 Vanguard, 600-699 and 800-899 DC-8, 700-799 and 900-999, DC-9.
Just because I stopped arguing, doesn't mean I think you are right. It just means I gave up!

It’s not higher numbers, it’s odds are outbound, evens inbound.

Do other airlines follow that system of numbering?

I have noticed Jetblue uses the area code for some routes..
Off the top of my head...
BOS JFK 917
BOS SAN 619
FLL HPN 914
PHX BOS 602
JFK SFO 415

Obviously not a steadfast rule, but it’s there...

For their transcons, JetBlue keeps the same last two digits and changes the first digits of the flight number.
For example, BOS-SFO is xx33:
B6 133
B6 1833
B6 633
B6 833
B6 333
Next flight: August 1: WN2002 BWI-MSY B737
SWA, UAL, DAL, AWE, ASA, TRS, DLH, CLH, AFR, BAW, EIN, AAL | E190 DC94 CRJ2 B712 B733 B737 B738 B739 B744 B752 B753 B762 B77W A319 A320 A321 A333 A343 A388 MD88

Almost every major US airline did this for decades. What obliterated it recently is in an effort to conserve flight numbers is airline assigning a roundtrip the same flight number in both directions.
