I like having a physical copy of my plane ticket when possible, but I don’t have a printer at home. I’m also trying to reduce the amount of paper I’m using so I get the airline app and screenshot the ticket.
Do this before you get to the airport, so you don’t have to deal with connecting to the internet.
It’s insane to me how many people will stand in line to get a ticket. Many airlines have kiosks, but I have been to the airport a few times when there were huge lines for those too.
Also, don’t rely on the gate numbers on the app or if you print your ticket at home. They can change! Check the screens when you get to the airport.
