Since I have your attention... couple more questions.... I've downloaded the app to have a boarding pass on my phone.... is that a good idea.... worth carrying the paper copies too?
And I notice you can check in online before the flight too? What is the purpose of that? I thought your check in was to say I'm here at the airport I want my seat?
I use a phone app but take paper copies... just in case.
Check in online and choose your seat. It saves queuing and you can go direct to security if you only have hand baggage,
