Nope. If you don't check in any bags and go straight to the gate we can't confirm you're at the airport, however if you are top on the list, you will be paged at the gate. If you do not respond to the page, we'll try the next one down.

Don't be afraid to ask any agents if we are looking for any volunteers to upgrade. If so, they can check with the controller to see if they've even started a list and if you may be considered. Just remember, free upgrades are not based on first asked first served. Pax that think that don't usually have any chance, unfortunately.
