For upgrades via the EUA process, please see: What is the Upgrade Hierarchy for EUAs?

After you have checked in for your flight you can check your position on the Battlefield upgrade list using the PDA site. Choose the "Flight Information & Status" link and then the "View Upgrade Standby List" option to search. If you are checked in for your flight and you do not appear on the list then you need to speak with someone at the airport to resolve the issue. Do not waste your time calling the reservations line or co.com support. They will see you in the queue for EUAs and insist that things are working correctly. It will be frustrating for everyone. Just don't bother. When you do arrive at the airport ask the agent to add you to the list. You can confirm using your mobile device as it will update immediately. If the agent does not know how to do it you can provide them with this code:
Note: At some point the last tie-breaker for Battle Field upgrades will switch from time added to the upgrade list to time of ticket purchase, with earliest being best. This is being done to bring it in line with the policy currently used for the EUA process.

Customers who have purchased (with cash or miles) a First/BusinessFirst ticket and are waitlisted for the front cabin will also be dropped from the waitlist 24 hours before the flight. However, such customers may be put on the PR1 standby list at the airport for their flight(s). For more information please see the following topics:
