ticket

I've requested a ticket on 4/7 but frankly it's full so I've to fly on the 5th, which I don't really want. Nevertheless, I've obtained the email to fly on the 4th. So I'm thinking of exchanging air ticket with someone who's going to fly on the 4th if that person doesn't mind to fly on the 5th.

But my name is specified in that email ticket which I'm gonna print. Does it actually matter? Since air-tickets don't specify names ryt... Helps pls...
