As I was quite vocal about my dissatisfaction with ABs performance over the recent months, here is my latest and greatest:
After 26 consecutive flights that were either delayed or cancelled, I am indeed noticing a massive improvement in since early June.
5 flights since then, and all of them were on time or minimally delayed (15 min or so, which is not really a problem for me).
So for what its worth in my experience as of today, the statements above don't seem to be PR wash only, but there is improvements happening indeed.
For the next couple of months I have taken my business to LH, but if the positive trend continues (and should AB still be around as such in autumn), I will gladly reconsider to fly AB again. Second chance.
