Most airlines are ticketless now, so if you've supplied an e-mail address they will have sent them there.
I will point out that you should always check the Junk mail folder before you delete. H4U sent my tickets and I found them in there
Note though, all the e-mail is a confirmation of your itinerary and your booking reference. Its not your tickets. Therefore, in the off chance you don't get them or indeed lose the sheet, then don't panic. You'll be able to board providing you have your passport.
99% airlines do this now (I've never had tickets for years other than my package holiday, just use me passport). Just took a while for package operators to catch on that we don't need a massive wedge of tickets.
Anyway, off there week today. Just took me folks to airport for there 3 weeks! Can't wait. Anyway, its hotter here as its raining over there!
