Delta Flight Upgrades — Frequently Asked Questions

How do I upgrade my Delta Airlines seat?
Delta seat upgrades can be requested at booking, after ticketing, or at the gate. Options include paying cash (the fare difference or a set upgrade price), using SkyMiles, or receiving a complimentary upgrade as a Medallion status member. Calling us is the fastest way to check upgrade availability and process the change in real time.
How much does it cost to upgrade a Delta flight?
Upgrade costs vary by route, cabin, and availability. Domestic Comfort+ upgrades can be as low as $30–$80. Domestic First Class upgrades typically range from $75–$250. International Delta One® upgrades can range from $400–$1,200+ depending on the route and timing. SkyMiles upgrades require 500–80,000 miles depending on the cabin and distance. Call us to get a live quote for your specific flight.
Can I upgrade using SkyMiles?
Yes. Delta offers SkyMiles upgrade awards for Comfort+, First Class, Delta Premium Select, and Delta One® on eligible flights. Award availability varies and is separate from cash upgrade availability. Medallion members receive upgrade priority. Call us with your SkyMiles balance and we'll check award inventory for your route.
What is the Delta Comfort+® upgrade?
Delta Comfort+ is a premium Economy section located at the front of the Main Cabin. It offers up to 3 inches of extra legroom, dedicated overhead bin space, early boarding, and enhanced snack/beverage service. It's the most accessible and affordable upgrade on most Delta flights.
What is Delta One® Business Class?
Delta One® is Delta's flagship Business Class product on international and select premium domestic routes. Features include fully lie-flat seats with direct aisle access on international flights, premium chef-curated meals, Delta Sky Club® lounge access, Westin Heavenly® bedding, and Tumi amenity kits. It's one of the best Business Class products in North America.
What is Delta Premium Select?
Delta Premium Select is a Premium Economy cabin available on select international long-haul routes. It features wider seats with more recline than Main Cabin, adjustable headrests and footrests, premium meal service, and priority boarding. It sits between Comfort+ and Delta One® in terms of price and comfort.
How do complimentary upgrades work for Medallion members?
Delta Medallion members receive complimentary upgrade priority on eligible flights when space is available. The upgrade window opens based on your status tier: Diamond members are waitlisted earliest (up to 120 hours before), followed by Platinum (72 hrs), Gold (48 hrs), and Silver (24 hrs). Higher status = higher priority on the upgrade list. Call us to check your upgrade waitlist position.
Can I upgrade a Basic Economy ticket?
No. Delta Basic Economy tickets are not eligible for seat upgrades at any time. If you want the ability to upgrade, you need to book Main Cabin or higher. If you've already purchased Basic Economy, the only option is to cancel (within 24 hours for a full refund) and rebook at a higher fare class. Call us immediately if this is your situation.
Can I upgrade an international Delta flight?
Yes. International upgrades to Delta Premium Select and Delta One® are available on eligible transatlantic and transpacific routes. Cash upgrade prices and SkyMiles requirements are higher than domestic, but the experience gap is also much larger. Our agents check live international upgrade inventory across all Delta hubs.
When is the best time to buy a Delta upgrade?
Upgrade prices are dynamic — they fluctuate based on demand and how far in advance you book. Generally, prices drop closer to departure as airlines try to fill premium seats. However, for popular routes (especially Delta One® international), inventory is limited and buying early is safer. Call us and we'll advise on the best timing for your specific itinerary.
Does Book Aero Fare charge a fee to process my upgrade?
No. Book Aero Fare does not charge an agency fee for upgrade assistance. You pay only what Delta charges for the upgrade — whether that's a cash amount or SkyMiles redemption. We transparently disclose all costs before processing anything.
Is Book Aero Fare affiliated with Delta Airlines?
No. Book Aero Fare is operated by People Information LLC, an independent travel agency. We are not affiliated with or endorsed by Delta Air Lines, Inc. We access Delta's inventory through global distribution systems as an authorized travel intermediary.
