Was giving the electronic boarding pass another go with my trip to montreal. Seemed like an ideal test case with free wifi at both airports. Went fine on the way over, but phone decided to hang just as I was crossing security on the Montreal side. Luckily it was pretty quiet and the security guard was understanding if a little unimpressed with the 5 minute reboot time. Still, might need a new/more reliable phone if I’m to trust it for a future run.
