we just booked and half of the group is class X on the way there, and the other half has class G. On the way back one half has class Q and the other has class B. What do these classes mean? From what I understand X and G both mean Econo fare, and Q and B both mean Flex Fare. so...
1) Whats the difference between Econo and Flex besides price?
2) Will we notice a difference?
3) Can we still be seated together?
4) Whats the difference between X and G class if they're both Econo?
Thanks in advance!
