E-ticket silly question
 

If you upgrade your flight and get a new e-ticket do you need to print that and bring it or is the old one good enough since it in the system?

sorry maybe silly question.

You don't, I never bring a printout with me, just passport

No but it will do no harm especially if there is a query.

I too have not been asked in years for the printout

Yeah that’s what I thought. I’m on the road so would be a hassle to print. Thanks guys!

I always keep a pdf copy of the e-ticket on my iPhone just in case I need to show anyone.

Yeah between the EK app and your e-mail on your phone there's really no need.

E-tickets are purely digital. All you can print is a receipt for an e-ticket and that does nothing for you. Certainly not in the past 5 years. The record will always be what is in the database no matter what you print out and try to show to someone. Just as an example, you could print your e-ticket receipt and then cancel your e-ticket. You would still have the receipt, but it proves nothing.
