Flights With The Same Flight #

Thu Aug 18, 2011 1:22 am

I notice that Delta flight DL2396 from CVG to SFO has the same flight # on the return from SFO to CVG the same evening. I happened to notice this as I'm on DL2396 from SFO to CVG tonight!
I am curious to know why the return flight doesn't have a different #.

Flights into and out of a hub often have the same flight #.

At DL, a lot of our flights have the same flight number, especially DCI turns. I know that, for one thing, DL is a little short on flight numbers at the moment, which is why they "cleaned up" their flight numbers a little bit ago to increase the number of available flight numbers.

Depending on the airline, of course. AC/QK does have a few flights that are the number same inbound from an outstation and outbound to another outstation (or from hub to hub), but they are in the minority. And unlike some of the major US airlines, all of AC/QK's "thru flights" are planned on the same aircraft, in and out (although that can change, pending operational requirements!).

CO has started using the same flight number on some turns as well over the last month or two. I have seen it from IAH-AUS-IAH, IAH-RSW-IAH, IAH-PHL-IAH, IAH-TPA-IAH to name a few city pairs. The same flight number in both directions is sporadic, but am sure it has to do with the merger.

Simplicity and limited flight number ranges.

Most major airlines will use the same flight number for certain turn-based routings for aircraft (as opposed to a thru routing)

This is a little different: most airlines have what's called "thru" or "direct" flights, where say a DL flight XXX will fly SFO-CVG-MCO

What the OP refers to is a flight YYY which flies SFO-CVG-SFO, where the flight number operates a turn instead of a thru routing.

It's also some kind of playing games with customers.

i.e. UA has flights with one flight number from FRA to HNL. They have "1 Stop in LAX". So they will show up higher in the GDS, since non stop flights (or direct flts) will show higher than flights with a "real" connection.

Furthermore pasengers usually think they do just land, people get off and on, and then they're in the air again. They usually don't realize that they're actually in need of connecting flights. I work for a IATA agent, people (at least in Europe, where it is quite unusual that different flights have same flt numbers) really think this. I do understand it may be different in the US, and also for us people here who know how this work, but for the average traveller this isn't the case.

And again, on some GDS those flights will show with higher priority, so I guess airlines using this are quite happy with "same flight number for different fligths".

The only instance in Australia I can find of this practice is Skytrans flight Q680. Cairns - Pormpuraaw - Kowanyama - Cairns. Everything else has different flight numbers out and in.

I have a few of these under my belt but the one I'm proud of is:

June 25 1961....CO flight 12 MKC-ORD B707-120
Oct 30 2009 ....CO flight 12 HNL-LAX B737-800

Using the same flight number on turn routings is a low risk affair anyway as there's no chance whatsoever of two aircraft being in the air at the same time with the same flight number since the flight inbound to the hub is to be operated with the outbound aircraft. So why not save a flight number for other purposes, especially when the mainline carrier assigns "blocks" of flight numbers to its regional affiliates and a block gets close to being fully used.

It is a very low risk for sure however, I have seen it happen where the flight departing the HUB was involved in a long delay and for whatever reason there was a crew and airplane at the out station with a few hour sit that was swapped out and had them changed so they flew inbound earlier. So rather than have two delayed flight and a pile of missed connects at the HUB, they only had one delayed flight and simply changed the flight number on the filed flight plan and the folks at the outstation got to the HUB on time. Pretty unusual for sure.

   Exactly.
