Cheaper fares and quick trips if it wasn’t delayed it was going to be perfectly fine and the seats space. It’s just to short I guess but I think next time I will upgrade to get more space

Wish it would've been clearer on what type of restritions the ticket had. Having to be forced to check my bag was unexpected.

Seats were horrible the gentleman in front of me reclined his seat even though he wasn’t supposed to from when we departed to when we landed!!
