I need help about acquiring boarding tickets using Expedia?

They will give you the boarding passes at the check in counter or at the check in machine, just make sure you have the proper ID.

Make sure you have your booking confirmation number too, just in case.

All you need is your ID- you do not need to bring anything else. For most major airlines there are 3 ways to check in and get your boarding pass:

1. You can take your ID to the check in counter and the agent will issue them

2. At the check in counter they have do it your self kiosks ( computer terminals) that allow you to use any credit card or a passport to check in and print your boarding pass

3. you can check in online and print your boarding pass from your home computer, or even on a smart phone - the display on your phone will have a scan-able optical code, so you show the TSA and the gate agent your phone.

and by the way: happy to help, but this belongs in the travel section.

Just take the itinerary, and post travel questions in the travel category in the future. You'd have to get boarding passes from the airline web site.
