Two reasons, firstly an aircraft swap at 0928 this morning. Your aircraft now assigned is G-TTNG inbound from VCE. It has an air traffic delay issued by Euro control due to Enroute weather, not Heathrow weather. That was 38 minutes. An earlier inbound emergency to LHR has meant Airborn holding is up to 27 mins on top of that.

It�s just pulling onto stand 520 or Gate A20.

I'm not sure about this? Certainly the showing departed but then sitting on stand for 10-20 mins is something I've come across a lot more recently.

it is how i always remember it showing with on time departures, but delayed arrivals due to slot delays. i am not sure i see any recent change here tbh.

Does anyone have any data on why this flight was delayed - it�s an AA code share. I missed my connection and ended up arriving 6 hrs late so just interested as the AA checkin desk said it was a high maintenance day but am conscious they may not have been given any helpful info and just assumed.
thanks in advance.

That's best covered in the AA forum, but AA1841 was marked as being late because of a late change in equipment on the previous service, CLT-MSY. In turn it looks like they switched to an aircraft that still had to arrive from DEN - this DEN-CLT service was on time but this was the aircraft that got allocated to CLT-MSY, presumably in the absence of anything else they could use.

BA910 FRA
BA1400 MAN
BA426 NAP
The above were late, on the day, cancellations.

BA285 SFO
That's a A380 so I'm sure that is TECY

Timekeeping today is pretty woeful, most departures and two-thirds of arrivals are running late today. Given that there are 341 departures scheduled (out of LHR 678) then I imagine that there may be some more cancellations this evening before the clock runs out on the day. Here is the ATC report and it basically says there is a bit of regulation around London (in bold) and other problems elsewhere. There were some areas of high windspeed at 3,000 this morning but that's ebbing away now.

Any idea why the BA1340 is cancelled tomorrow? Have friends coming over to JER for the weekend and now they can�t get a flight until tomorrow evening 😑.

Any ideas why this flight tomorrow is cancelled?, I was due to do a day trip coming back on the last flight. BA rebooked me onto BA1336 which was the same plane I was due to fly back on.

Thankfully they cancelled it early enough that I have rebooked to this evenings flight (BA1338) but now need to pay for a hotel in Newcastle tonight.

Im assuming that I�ll be eligible for compensation for the cancellation but not expenses for the hotel (since I have now chosen to go the night before).

I�m sitting in the CCR feeling a bit indifferent about my Munich flight later - arriving after midnight seems tricky with their local curfew, and maybe a night in a hotel here would be better than a late night trek from Munich airport�

Presume compensation would be out given earlier text on ATC restrictions (boo!)

�Forecasted adverse weather conditions in the London area� according to the email/text I�ve just received.

travellingowl

BA just emailed me and said the following�.

We�re extremely sorry that your flight has been cancelled at short notice. This is due to forecasted adverse weather conditions in the London area.

Does this mean that they will deny any compensation claim?, if it�s weather conditions that limits flow then surely they�ve made a commercial decision to cancel this flight?

corporate-wage-slave

I can't see what the specific issue is tomorrow, the weather forecast seems benign. But the most recent posts above are in line with a HADACAB warning, and in that scenario either flights get cancelled pro-actively, or if they don't it will be re-active cancellations when the delays have all built up. Ultimately it's weather related, or strictly speaking weather forecast related, and I can't see EC261 compensation being payable. It certainly is not payable if it's reactive cancellation. I guess your argument would be that by being proactive BA is making to some degree commercial decisions as to which flight to chop, but the fact is that if the weather forecast was ok there would be no cancellation.

If / when I see an alert for LHR then I will update here on the exact reason for these cancellations.

Unrelated, but the reason for the delays today was another airside emergency - I don't have the details - which resulted in very congested hold patterns, some stretching to 30 minutes.

forgive my ignorance but what does this show in relation to departures from Heathrow tomorrow?

Heathrow Tower

In basic terms, the airspace in blue has been regulated, so a cap on hourly movements has been applied. Any departures out of London heading S and SE will be affected, and will be delayed by the allocation of ATC slot times.
