Editing Boarding pass (section)

===Drawbacks===
*Using a mobile boarding pass is risky if one's phone battery runs out (rendering the boarding pass inaccessible) or if there are any problems reading the e-boarding pass.<ref name="letsflycheaper" />
*Using a mobile boarding pass can also be a challenge when traveling with multiple passengers on one reservation, because not all airline apps handle multiple mobile boarding passes.<ref name="bare_url" /> (However, some airlines, like [[Alaska Airlines]], do allow users to switch between multiple boarding passes within their apps.)
*Some airlines (and even a few government authorities) may still require some paper portions of the boarding cards to be retained by staff.  This is obviously not possible with a mobile boarding card.  
*Some airlines need to stamp a boarding card after performing document verification checks on some passengers (e.g. Ryanair).  Some airport authorities (e.g. Philippine immigration officers) also stamp the boarding card with the departure date.  Passengers in turn have to present to staff their '''stamped''' boarding card at the gate to be allowed to board.  As such, airlines may not extend the mobile boarding card feature to all its passengers within certain flights.
