Will my boarding pass automatically update if there are involuntary changes made to my flight?

Yes, your mobile boarding pass will update if there are changes made to your flight. 

We recommend being at the gate well ahead of your flight. We will usually begin boarding about 45 minutes before departure time, so it’s important to be at the gate and ready to board at least 45 minutes prior to scheduled departure.

Remember, your gate assignment and departure time could change due to operational requirements. You can easily stay updated by checking the flight monitors at the airport and by checking your Flight Status.
