When you book a flight with Endeavor Air, you are actually entering the world of Delta Air Lines. As a wholly-owned subsidiary, Endeavor operates exclusively as a Delta Connection carrier. This means that if you are looking for the Endeavor Air Flight Change Policy, you won’t find a separate rulebook on Endeavor’s website. Instead, your travel is governed by Delta’s ticketing rules, customer commitment, and digital platforms.

Whether you need to push your trip back by a week or swap a morning flight for an evening one, understanding how these "big-league" rules apply to regional flights is the key to a stress-free modification.

The Delta-Endeavor Connection: Who Handles Your Change?

Because Endeavor Air is essentially the "operational arm" for Delta’s regional routes, they do not have their own reservations department for the public. Every ticket is sold, managed, and serviced through Delta.

• Website & App: You will use the Delta website or the Fly Delta app to make any changes.

• Customer Service: If you need to speak to someone, you will call Delta’s reservations line (800-221-1212), not an Endeavor office.

• Ticket Numbers: Your ticket number will almost certainly start with "006," which is the airline code for Delta.

Change Fees: The Landscape

The most important thing to know about the Endeavor Air Flight Change Policy is that "change fees" are largely a thing of the past for most domestic travel. In an effort to keep up with industry trends, Delta (and by extension, Endeavor) has eliminated change fees for many tickets originating in North America.

1. Main Cabin and Above

If you booked a Main Cabin, Delta Comfort+, or First Class ticket, you are in the "no change fee" zone. You can change your flight as many times as you need without a flat penalty.

• Fare Difference: While there is no fee to make the change, you must pay the difference in price. If your new flight is $50 more expensive than your old one, you’ll pay that $50. If it’s cheaper, you’ll receive the difference as an eCredit for future travel.

2. Basic Economy: The Restriction

Basic Economy is the major exception. These tickets are designed to be the lowest price possible, and that comes with a trade-off: they are generally non-changeable.

• 24-Hour Rule: You can still cancel or change a Basic Economy ticket within 24 hours of booking for a full refund (as long as you booked at least a week before departure).

• After 24 Hours: You typically cannot change a Basic Economy flight. If you can't make the trip, you may have to cancel it for a partial eCredit (minus a cancellation fee) and then book a new ticket entirely.

Same-Day Flight Changes

Sometimes you don't need to change your trip to a different week—you just want to get home earlier on the day of travel. This falls under the Same-Day Change rules.

• Same-Day Confirmed: For a flat fee (usually around $75, but waived for certain Medallion elite members), you can confirm a seat on a different flight on the same day as your original departure. The new flight must follow the same route.

• Same-Day Standby: If a confirmed seat isn't available or you don't want to pay the fee, you can wait at the airport for an open seat on an earlier flight. There is usually no charge for standby unless you actually clear and get a seat.

How to Modify Your Schedule: Step-by-Step

Since you are dealing with Delta’s systems, the process is very digital-friendly.

Step 1: Access "My Trips"

Go to the Delta website or open the Fly Delta app. You will need your confirmation number (six characters) and your last name.

Step 2: Select "Modify Flight"

Once your itinerary is open, look for the button that says "Modify Flight." You will be given the option to either "Change Flight" or "Cancel Flight." Choose "Change."

Step 3: Pick Your New Dates/Times

The system will show you a list of new flight options. It will clearly display the "Additional Collection" (the fare difference) or the "Credit Due" for each option.

Step 4: Confirm and Re-issue

Once you select the new flight and pay any fare difference, your ticket will be re-issued. You should receive a new confirmation email immediately.

What Happens During Schedule Changes?

Occasionally, the airline is the one that changes the schedule. Because Endeavor operates smaller regional jets, their schedules are more prone to "tweaks" than major mainline routes.

If the Endeavor Air Flight Change Policy is triggered because of an airline-initiated change (e.g., they move your flight by more than 120 minutes), the standard rules are tossed out. In this case:

• You can change to a different flight within a certain window (usually +/- 2 days) for free, with no fare difference.

• If the new schedule doesn't work for you at all, you are entitled to a full cash refund, even on a non-refundable Basic Economy ticket.

Final Takeaway for Travelers

Navigating the Endeavor Air Flight Change Policy is essentially the same as navigating Delta's. If you have a standard Main Cabin ticket, you have a lot of flexibility. Just remember that regional flights can have fewer daily options than major routes, so if you are changing your flight, try to do it as early as possible to ensure there is actually a seat available on the alternative flight.
