This post is going to sound very similar to my last one, but now I only want to make sure I can check-in online from my desktop, download both the qr code and boarding pass as a pdf file to my phone and then either board the plane showing my phone with the pdf boarding pass to the agent or use my phone and the pdf qr code with the kiosk to print the boarding pass and board the plane.
I got all steps right, right?
Everything I can do with the airline app in my phone I can do with my desktop, right? The airline app is the same website with a different format, it doesn’t give me anything special, right?
Every time I’ve checked in online the qr code is the boarding pass so there’s no need to go to the kiosk, they check it on your phone. But as the others said it may vary depending on airline or country. And you probably don’t need the app at all unless the website says otherwise.
