Everything went smoothly, but when I have read their contract, I've found they are agree to pay no more than $8 per kilo (about two pounds) in case your luggage get lost. And the food ("Enjoy your meal") is a junk.
Avoid school holidays: Many cheap airlines take advantage of school holidays to increase their prices, as they expect to have a larger number of passengers than usual. During these periods a late booking (1 week before departure) may result in your paying more than the price of a ticket with a regular airline. It is therefore advisable to avoid these periods, if possible.
