some airlines will send your tickets to you by post or courier. but not sure for your online booking, just give them a call to ask lor. have to make sure whether your booking summary is so called e-tickets.
If you booked your ticked using your aeroplane reward, you will receive a package exactly the same as your printed booking summary.
Because it's e-ticket, so everything is in their system.
You just need to present your photo-ID and your aeroplane card while checking in. You can bring either the package or the printed summary just in case something goes wrong.
Normally, you don't need to confirm your e-ticket but for sure, you can double-check with them.
