You above all people, judging by your previous posts, must be aware that it does not follow that because a flight departs on time today, with the tech issue TCX had earlier this week that there is not still an outstanding impact on the rest of the programme. One aircraft may still be AOG and no departure board is going to tell me that is it? Yes it was a serious question and thanks to the person that PM'd me with a serious answer!
Serious Answer.....
Here is mine: When are you travelling? Today? because if you are not then it is totally irrelevant whether the "longhaul" programme is on time or not.
Aircraft can suffer knock on delays from any destination....any tech issue at any time.....
ask the monastir-glasgow passengers who were about to board their 757 home on sunday morning, only to suffer an unexpected delay of 8 hours!
it is an irrelevant question as it will have zero effect on any flight you are about to underatake
