Also, SkyMiles Members traveling on a
Delta e-ticket for a domestic flight can use our self - service
kiosks in more than 80
airports nationwide to quickly check in for a flight or standby for an upgrade.
First Class,
Delta Comfort + and Preferred Seats purchases and paid Premium class upgrades, made through a
Delta channel (including
delta.com, Fly
Delta mobile app,
Delta Reservations,
Delta kiosks, and select
Delta airport locations) are included in MQDs.
If you choose to opt out of Complimentary Upgrades, you may select an available
Delta Comfort + seat off of the seat map * in the Fly
Delta app or at
delta.com, as long as you are within your eligibility window, and starting June 15, 2017, when traveling alone, Medallion Members who are not opted in to receive automatic
Delta Comfort + upgrades will now have the ability to request a
Delta Comfort + upgrade to any available seat or only a window / aisle seat when checking in for a flight at
delta.com or at an
airport kiosk.
