I was going to post in the US forum, but this really isn't US-specific. I was scheduled on 4118 from PHL to IPT this morning. It cancelled. The return, 4118 from IPT to PHL, which uses the same aircraft (there being 3 commercial flights daily to this airport and there not being any alternative), is still showing on time 70 minutes before departure. Edited to add - US does, it turns out, have an extra DH8 on the ground at IPT. So why did it lie to ME about my flight being on time when I was at the RCC and cancelled as soon as I got to Terminal F? Just ranting.
