Delta Flight Question

Sun Jun 26, 2011 12:59 am

Since I was on this flight and I just wanted to go back and look at my flight path, I noticed something odd about this flight.

DL2363 LAX-JFK is the 11:40 red-eye. What I was curious is, is does anyone know why the flight number was changed to DL9798. The only explanation I'm coming up with is the fact that we had the remains on board of a US Soldier killed in the Middle East but I didn't realize this was a reason to change the flight number considering that the other leg that uses this flight number arrived on time. Any ides why it was changed or if it was in relation to the remains onboard (that we were not made aware of until we landed in JFK and were greeted by about 100 police and fire vehicles), why they would change the flight number?

Would need the date that you traveled.

Nevermind, I see it was on the 21st. Anyway, it was an OPS thing. Your flight was actually without an a/c because the of the late arrival of DL 2363 coming from JFK. they chose to go with an a/c sub instead of waiting for 2363 to block in. By doing this, you can't have the same flight number being used for two different operations at the same time. To get around this, they come up with a "dummy" flight number to get the dispatch paperwork going for your outbound leg.

Hope this all makes sens.

That'd be helpful wouldn't it. It was this past Tuesday, the 21st (though the flight technically didn't push until after midnight I believe)

I understand that perfectly.

I was aware that you couldn't have 2 flights with the same flight number airborne at the same time but I didn't think that the dispatch paperwork would get hung up on that.

In some respects companies often did, NW say if flight 1776 PHL-MSP-GEG and the PHL-MSP was going to arrive after the MSP-GEG flight left, the flight going to GEG unbeknownced to pax would become 1776N until 1776 landed and blocked in, then the flight that was given 1776N would then just become 1776.

That makes sense but DL almsot always seems to go with a 9XXX flight number whebn there is a possible conflict, thus the flight "stub".

In this particular case, the same a/c is scheduled (suppose to anyway) to fly the return 2363 to JFK but with the ground delays in NY, the a/c is late into LAX a lot and they often have to get a spare a/c to fly 2363 LAX-JFK. With Alasizon, his a/c was out the gate before the original scheduled inbound a/c on 2363 JFK-LAX blocked in. It would have been quite the delay.

Yep. First issue would be getting the weight and balance done through the DL system. Can't get any of that done until there is a load plan done and this can't be done because the dispatcher won't be able to do his thing until JFK-LAX was blocked in the gate. So, the decision comes from ATL OPS to either take the delay and use the inbound a/c or use one of the spare a/c they have to operate your flight, but then we have what you saw with the 9000 flight number.
