What Exactly Is a Delta Flight Number?
A Delta flight number is a unique identifier that combines the airline’s two-letter code—DL—with a numeric sequence (e.g., DL452, DL1209). It’s assigned to a specific route on a given day and helps airports, apps, and airlines track your itinerary with precision.
Flight numbers typically range from 1 to 4 digits. Lower numbers are often reserved for major domestic or transcontinental routes, while higher numbers may be used for regional or international flights.

Where to Locate Your Flight Number on Your Booking Confirmation
After you’ve booked your flight, your confirmation email or e-ticket will list the flight number clearly, usually near the top, under flight itinerary details. Look for something like "Flight: DL1637" next to your departure and arrival cities.
If you printed your receipt or saved a PDF copy, the number will also be visible near your travel dates. Most mobile receipts and wallet passes also display the flight number in bold. (Support No: 877-297-0699

Using Your Flight Number for Airport Monitors and Flight Tracking
Flight numbers power everything from baggage claim screens to gate announcements.

Flight Numbers for Connecting or Multi-Leg Journeys
Each flight segment will have its own flight number.
Example:
DL1614: NYC to Atlanta
DL197: Atlanta to San José, Costa Rica
Always use the next flight’s number when checking in or verifying gates mid-trip. For baggage claim or missed connections, this distinction becomes vital.

International vs. Domestic Flight Numbers: Is There a Difference?
Yes.
Domestic flights tend to have 3- or 4-digit numbers.
International routes, particularly long-haul ones, may feature lower, legacy numbers (e.g., DL1, DL6) for flagship services.
The formatting is uniform, but international flights may also include codeshare equivalents with Air France, KLM, or Virgin Atlantic—especially within the SkyTeam Alliance.

How Flight Numbers Can Change and Why It Happens
Sometimes your flight number may shift due to:
Aircraft substitutions
Schedule changes
Codeshare realignments
Always recheck 24–48 hours before departure. The Fly Delta app or Delta.com will notify you of any changes automatically if you’ve added your trip.
