Thanks everyone for your reply! It is a us airways ticket operated by ba. I called us air and they told me I would make it! I did everything I could to change it so I would have more time but it would cost me a lot. I bought the ticked by mistake. I mean, I didn't see that there were 2 different airports in London in the ticket. Us air said it was a " Real" connection, one ticket. I have booked a prepaid taxi transfer and they should be waiting in arrivals in t5 and driving me to t3 in Gatwick. I arive at Heathrow at 8:25 Saturday and live from Gatwick at 1155 to Las Vegas. I'm gonna stay in Vegas 3 weeks so I'm gonna need to check my baggage in
