We flew out of Barcelona with a connecting flight in Dublin to final destination in Chicago. At check in in Barcelona which included two checked bags we were only given a paper boarding pass just for the Dublin flight and not the connecting flight to Chicago. We did however have an online boarding pass down loaded on our phones, but not all the information was correct. When we got to Dublin we inquired about getting a paper boarding pass again, but were told that the electronic pass is all we needed. That was technically true, but handling the phone with our carry on baggage and going through 3-4 check points was difficult to juggle everything at the check points. I really wish I had been given a paper boarding pass. When looking through the long lines at the various check points, I did not see one other passenger using their phone as their boarding pass. I wish we had been given a paper boarding pass in Barcelona for both flights!
