This tip could save you a lot of stress when it comes to checking-in
In recent years, I've become a fan of using a mobile boarding pass, which is retrieved through a link sent via text or email.
Most airlines offer the option of a mobile boarding pass as an alternative to printing yours or picking up a paper copy at the airport. It can be particularly useful if you're not near a printer, or don't want to waste time in a long check-in line at the airport. But this method has one big downfall.
About a year ago, I was rushing through a foreign airport, trying to make a tight connection that required me to clear customs and then get through a second security screening. I was using a mobile boarding pass the airline had sent me, but when I went to pull it up on my phone, it wouldn't appear.
I realised that the airport not only didn't have Wi-Fi, but my phone had no signal. I couldn't open the boarding pass link, and I was as good as ticketless, standing on the wrong side of security. In a panic, I ran outside to see if I could get a signal; it worked and I was able to pull up my boarding pass, then sprint back to security and make my flight.
