This is a photo I took in Zurich airport recently. The tv screen says Boarding at 15:00 while the clock on the right (correctly) shows the time as being 15:15. We didn’t get to board until nearly 15:25.
Even in Switzerland, where everything is supposed to run like clockwork, Aer Lingus manage to be late.
You wouldn’t mind so much if they only told us what was going on and when we were likely to be boarding.
