Delta is one of the nation's largest airlines. When flying with Delta, there are several different classes of seats. The bulk of the seats are coach (also referred to as economy). These seats offer limited thrills and often charge you additional fees for just about any extra (such as snacks and alcohol). However, it is possible to upgrade to first-class seating in the plane. This comes with additional leg room, larger meals, often free cocktails and more service.
Purchase the first-class upgrade when buying the tickets. This is the most sure way to secure an upgrade on the flight.
Ask if the flight is overbooked when you arrive at the airport. If so, you may request to be upgraded to first class for free.
Purchase a first-class upgrade when checking in for the flight if you are not allowed to upgrade for free. This is usually the same price as purchasing the upgrade online when you initially bought the tickets.
Talk to your flight attendant. If there are seats available and you are polite, the attendant may allow you to move up to first class (especially if your seat is cramped due to other individuals around you, or due to crying children next to your seat). Make sure you are dressed professionally as the airline is less likely to give you the upgrade if you look like you just came back from a backpacking trip and are dirty or wearing torn clothes.
