There are a few different ways to upgrade to first class on Delta.

 Upgrade with miles

 You can use your Delta SkyMiles to upgrade to first class on eligible flights. The cost of an upgrade varies depending on the flight, but it typically starts at around 25,000 miles. You can upgrade your flight online, through the Delta app, or by calling Delta Reservations.

 Use an upgrade certificate

 If you have a Delta Medallion status, you may be eligible to receive upgrade certificates. These certificates can be used to upgrade your flight to first class for free or at a reduced cost. To find out if you have any upgrades to first-class Delta airlines , log in to your Delta account and check your My Certificates page.

 Be on the upgrade list

Even if you don't have miles or an upgrade certificate, you can still be upgraded to first class by being on the upgrade list. When you book your flight, you can choose to be placed on the upgrade list. If there are any empty first class seats, you will be upgraded on a first-come, first-served basis.

Upgrade at the gate

If you are flying on a Delta Medallion level, you can also upgrade to first class at the gate. This is a great option if you have a last-minute change of plans or if you are flying on a popular route.

Upgrade with cash

If you don't have any miles, upgrade certificates, or status, you can still upgrade to first class by paying for it with cash. The cost of an upgrade varies depending on the flight, but it typically starts at around $500. You can upgrade your flight online, through the Delta app, or by calling Delta Reservations.

Tips for getting upgraded

There are a few things you can do to increase your chances of getting upgraded to first class:

• Fly on a Delta Medallion level. Delta Medallion members are given priority on the upgrade list.
• Book a flexible fare. If you are willing to pay a little more for your ticket, you can book a flexible fare that allows you to change your flight without paying a fee. This will give you a better chance of getting upgraded if there are any empty seats.
• Be flexible with your travel dates. If you are able to fly on a less popular day or time, you will have a better chance of getting upgraded.
• Check in early. The earlier you check in, the more likely you are to get an upgrade.
• Be nice to the gate agent. Gate agents have the power to upgrade passengers, so it doesn't hurt to be friendly and polite.
