Well I talked to the office and they told me they're just BP style but actually they're tickets. I show them at the check-in before each flight and they'll cut the right corner, to give me the boarding pass. They're just flight coupons. At last I think this is a more comfortable way for the traveller to be on the road with this thin amount of tickets than going with a thick bunch in the pocket for the long haul.

They've also confirmed that my AA number is on the booking, they tell is no problem that it's not written down on the ticks...

thanks to you all, I was a little bit worried with that!!!
