I tried to use an electronic BP last trip and it turned out paper would have made things better. Was flying out of LGA on Am. Eagle on June 27th or whatever day that FA went crazy on one of the flights. Was going to leave out of C gates, but went to meet someone at the lounge in D. Went back to C to board, and after a big mess, the flight got cancelled. No one at the gates, no announcement. Was going to go back to the lounge to try to get things sorted out there, but the electronic boarding pass disappeared because of the flight cancellation, and I couldn't get back into D to the lounge.
