I self checked into westjet for my flight, now what?

I fly out from Winnipeg to Calgary then to kamloops in about 20 hours, I used the web to self check in for my flights and reserve my seats. I got the emails with the barcodes. But what do I do next? Once I arrive at the airport what do I do now? How do I check my bag? Do I need to have anything printed?

The emails said not to print the barcodes out. So I'm assuming that security and so forth will simply scan the code off my iPhone. Right?

If you have a barcode to display on your phone, that should be all you need. To check a bag, look for a counter called bag drop or something like that, show them your barcode, and they should be able to tag your bag and send it on its way. Then head for security and your gate.

With airlines changing rules on a daily basis about checked and carry-on luggage, it is sometimes hard to keep up. Plus, the rules for domestic travel are different than they are for international travel. When in doubt, check with your airline for the latest information.
