Mobile boarding passes are not just allowed at Heathrow—they’re practically encouraged. The airport has invested in scanners that read phone screens perfectly. The only real barriers are your phone’s battery life and your airline’s specific rules. So check your booking confirmation, charge up, and you’re golden.
And if you’re still worried? Just think of my 5:30 AM sprint. I made it. You will too. Now go download that boarding pass and stop printing things like it’s 1999.
Safe travels, and don’t forget to turn on airplane mode.
