What changes between these airlines
Delta publishes some ordinary and excess fee rows, while United directs travelers to an itinerary-specific checked-bag calculator. A missing United price in this site is a quote gap, not a cheaper bag.
| Airline | When it applies | Standard bag limit | Published fee example |
|---|---|---|---|
| Delta Air Lines | Standard U.S. domestic baggage; eligible fare and benefit checks remain necessary. | 50 lb; 62 linear in | $45 first bag, $55 second bag and $200 third bag. |
| United Airlines | Itinerary-specific calculator; no fixed current United rate was extracted. | No directly comparable limit confirmed | Check the airline for a price |
The examples above may use different routes, fares, or dates. Don’t subtract one from the other as if they were quotes for the same flight. Use the interactive comparison for your own bag, then open both airlines’ booking flows for the final charge.
Compare your own trip
- Find the fare on each ticket and the airline flying each leg.
- Compare the same bag number, weight, and outside size for the same traveler and direction.
- Keep taxes, currency, and purchase timing in view. If either airline needs a booking quote, you don’t have a reliable price difference yet.
