to arrive at 11AM on a Monday and leave at 8PM on Friday. Then 2 weeks after I booked the tickets, they changed the flight times so that I would arrive at 1AM on Tuesday at leave at 6AM on Friday. Would have killed 2 full days of the vacation.
Luckily I was able to cancel for a full refund after the flight change so I never actually even flew with them. But that was enough to put a bad taste in my mouth.
