I'm taking the Amtrak from Santa Barbara to Burbank airport, and then flying southwest to Vegas. The train arrives at 9 a.m. the first flight to Vegas after that time is 9:50 and the next one is at 11:25. I'm wondering if I should risk it and book the 9:50? I plan on checking in online the night before and printing my boarding pass, and not checking any bags. I know it's cutting it close, but since it's a small airport, and on a Thursday, I wonder if it's possible? Also, if I did book the earlier flight and ended up missing it, does it cost a fortune to get on the next available flight?
