From what's been reported the wrestlers pay for they own flight but, if you're a main eventer the WWE pays for your flight in 1st class. Which is why they got piss that Billy Silverman got first class tickets never mind the fact he paid for them himself. But, then X-Pac was always flying in 1st class around that time to and lord knows he was anything but, a main eventer at the time.
That can't be right. I've read WWE pays for the wrestlers plane tickets and the tickets are either mailed to the wrestlers home or they pick them up at the airport. The rental cars and hotels are paid for out of the wrestlers pockets.
I know Lance Storm did a column or answered this on his message board around the time of the Billy Silverman stuff. The Torch (Dave) also wrote about it. They said midcarders get coach and it's possible to bump them up to first class if they pay for it out of their own pockets, but it's looked down apon. It's one of those WWE unspoken rules that only management, veterans and main eventers can fly first class and if you dare break these rules Bradshaw fucks you in the ass or you get on Taker's shit list.
Other promoters pay for tickets as well. Jesus, how many guys complained Heyman never got their tickets to them? That's why smaller promotions like guys to live around their main territory. It saves money.
