It’s a discount flight so you have to expect to be crammed in. Then there is the food strike at a supplier we were all warned of and they were good with snacks. The attendants were great. I’ll fly them a hand I recommend them, for what they are.

It’s a discount flight so you have to expect to be crammed in. Then there is the food strike at a supplier we were all warned of and they were good with snacks. The attendants were great. I’ll fly them a hand I recommend them, for what they are.
