AA39 LHR - MIA cancellations
We are due to fly on this route in the next week and have been keeping an eye on departure times, for the last few days the flight has been cancelled.

Does anyone know why? Is this due to capacity issues at LHR?

Thanks in advance.

Thank you. Forgive my ignorance but does this mean that the original flight was cancelled but all were booked onto an alternative and that flight was completed?

This is how AA has been handling aircraft substitutions. The original inbound flight AA38 on a 77W gets cancelled and a replacement AA9600 (on Monday, AA9604 today) on a 772 gets created and flown with as many reaccommodated as possible.

Indeed. This has been especially true with routes that utilize the 77W, since they cannot simply swap in another one-for-one 777 replacement. The 77W becomes a 772 and the pax are re-accommodated as best they can. This happened to me about a month ago LHR-DFW. And it happened again last night with AA79 DFW-LHR. Currently operating as AA9601 as I type this.

The way to find these replacement flights if you see a cancel is to do a flight status search between city pairs.

Thanks, that’s very helpful. I can now see that a replacement flight with a 772 has operated each day.

Has there been recent known dispatch reliability issues with the 77Ws?

Actually last night's (19 Jul) AA79 replacement flight (AA9601) was flown by a B789. Quite a downgauge. Might have been an outlier but it goes to show there's no set answer.
