was able to switch out 11/19 to 11/17 for 7 ppl! worth it since I had a 5 hour layover, i gain 2 full days. I also changed another ticket I had in march for 2 ppl from mon nt to sat nt. I told them I wasnt ready to decide about the return yet they said I can still call till 8/31 and change that portion
bottom line very accomodating!
