Looking to book 4 first class tickets CLT-LAS for March 8th-12th 2020 right now they are running $937.00, which seems to me low as they may get. Anyone offer any experience or advice as what is a good "lock in" price? don't want to book to early or book to late either. what is the average price you have seen for first class that time of year? I know March is a busy month and feel like I should jump on these now but don't want buyer's remorse later lol help!?
