Go to Delta's official website (delta.com) and look for the "Manage My Booking" or "My Trips" section. This is typically found on the homepage.
If you booked your flight while logged in, you can sign in to your account. If not, you may need to retrieve your booking using your confirmation number and the passenger's last name.
Enter the required information, which usually includes your confirmation number and the last name of the passenger. Click on the "Find My Trip" or similar button.
Once you've successfully retrieved your booking, you should have access to details such as your flight itinerary, seat selection, and other relevant information.
Depending on the options available, you may be able to make changes to your flight, such as selecting or changing seats, updating contact information, or modifying your meal preferences.
You might have the option to add extras, such as extra baggage, in-flight services, or other amenities.
If your departure date is approaching, you may be able to check in for your flight through the "Manage My Booking" section.
Before finalizing any changes, carefully review the details to ensure accuracy. Follow the prompts to confirm your modifications.
