DO NOT use any of their 'extras' as it's just a way to rip you off. They charged for seat assignments but airlines doesn't allow selection of seats, so paid for something we did not get. They are in the business of booking flights, they know which airlines allow this and which ones do not. They have an icon on the first booking page showing what's available and it shows seat selections as available, but they are not! Then they say you're paying a fee for them to request the seats for you and not for the seat itself - scammers.
