Check in opens early enough to be able to print off boarding passes before you go on holiday
Check in is usually a quick process owing to having plenty desks open so limited queuing at airport which is fantastic.
Range of goods is average but difficult to have too much choice anyway and the food and snacks are tasty enough.
When at destination again they have adequate staff so no messing about at airport when you land.
Reps at hotel site daily so again always good to see if they are required.
Space on planes is better than some other travel companies so there is space for legs.
Having to pay to prebook seats (but all travel companies cheat you that way)
make sure you check in online if you book it that way or will be charged at airport.
