This question already has an answer here:
When I'm busy, checking in to my flights via the web is often convenient. I get my boarding passes sent right to my phone and I don't need to worry about printing them before arriving to the airport. However, I also like collecting physical copies of my boarding passes. They're cool momentos of my travels more than anything else, and when I get the chance to print them out, I typically do.
My question is, if I've already checked into my flight on my phone, can I print another set of boarding passes at the airport? I do like the official airport paper ones most.
To make this question more general, consider the unfortunate situation of your phone dying. Having a backup physical copy of your boarding pass could save the day.
In essence, is there anything stopping me from making another boarding pass at the kiosk after I've checked in beforehand?
