  1. [R2] Fly Delta 5/5 · US Fantastic app. Get it: Do not screw this app up! Great communication from delta to your phone. I’m sure if they could carry you to the terminal the app would. Fast comms when you need to see your gate. Love this app!!!!
  2. [R3] Fly Delta 3/5 · US Good but Needs Work: I like the general user interface. However, often times when I’m searching for flights, I will plug in all the info and the “find flights” button just doesn’t work. It’ll ‘click’ but but not even attempt to load to a new page.
  3. [R5] Fly Delta 4/5 · US Why did you delete the Concur functionality from the app.: They deleted the Concur functionality from the app. Please bring this back!
  4. [R6] Fly Delta 3/5 · US Dark mode: Add dark mode in the app
  5. [R1] Fly Delta 1/5 · US Horrible app, horrible costumer support: Super buggy. Always gives error messages. Useless. Not very different from Delta in general.
  6. [R7] Fly Delta 1/5 · US Login isn’t working: I have several hours before my flight and I can’t login. Not in app or on website. Customer support is dead silent. Nice…
  7. [R8] Fly Delta 5/5 · US Such a wonderful user experience: This is simply a wonderful app. I recently experienced 3 flight delays due to thunderstorms across the east coast. The Delta app immediately sends me a gate change update via the mobile app and text message. It has the most accurate flight information, so I don’t have to read the possibly outdated flight boards at the airport. I love how easy it is to access board
  8. [R9] Fly Delta 3/5 · US Login process sucks: The login on the app barely works at first
  9. [R11] Fly Delta 4/5 · US Boarding status?: The app does not provide current boarding status, including the zone that is actively being boarded
  10. [R27] Fly Delta 3/5 · US Can’t tell me gates: Like: I can add the ticket to my wallet. Dislike: It can’t tell me gates my flights depart from. I have to screenshot my ticket and ask Google for the gate.
  11. [R33] Fly Delta 3/5 · US Decent but bug issues: The app is mostly great. The promos tab can’t be accessed from at least my app. The loading page has a “seizure” and my dashboard in the app shows the wrong amount of points. This has been going on for months.
  12. [R14] Fly Delta 5/5 · US Best airline app in the US: I fly constAntly and have top level status on all major IS carriers. Delta’s app is superior and beyond comparison. You literally never have to call the 1-800 number unless there are very unusual circumstances. As with all things regarding Delta, it’s the best in the industry and the best in the country and they continued to improve every day. I love this airline, I lov
  13. [R19] Fly Delta 2/5 · US App Not Updating Trips: Since mid June 2026 my trip feed stop updating. I thought Delta would fix the issue soon but no it still continues to be an issue. I’ve deleted the app and reinstall and made sure there are no IOS updates too, still didn’t work. I contacted Delta and despite being a Diamond Medallion trying to help, the customer service folks I spoke with said they couldn’t help and told me
  14. [R18] Fly Delta 3/5 · US Decent but a frustrating experience compared to what’s possible: To the ostriches in the Delta software department who think someone might steal my phone and board a plane after 10 minutes of app inactivity: go kick some rocks. Maybe I just want to check my connection or gate info, which might impact how I approach my layover, but no - I get logged out and can only use the app for checking if my p
  15. [R29] Fly Delta 4/5 · US Login Every Time: Generally, the app is very good and I can accomplish what I want to. But since the last major update, I now have to log into the app every single time that I open it. And there are times, especially in airports, when connectivity isn’t that great and logging in can be hard to do. I wish they would go back to the previous version where it preserved your credentials.
  16. [R45] Fly Delta 3/5 · GB Can’t download boarding passes to wallet: Well having tried several time to download my boarding passes to apple wallet, keep getting an error message, this needs sorting out admin.
  17. [R66] JetBlue 3/5 · US Generally Good: This app does much of what is intended: it allows you to search and book flights easily. Where it fails is in flight check-in. Most of the time, it doesn’t allow the check-in to happen with a snappy message: It’s not you, it’s us! Well, if it’s you, then FIX IT! And it does this for most of the flights I have taken.
  18. [R82] JetBlue 1/5 · US Can’t add to wallet: Can’t add to wallet
  19. [R40] Fly Delta 1/5 · US Too many failures: This app is trash. It constantly logs me out and then gives error messages when I attempt to log in
  20. [R15] Fly Delta 3/5 · US I’m trying to give you money: Just bugs everywhere trying to add seats. You have one flow that lets you upgrade, but the wording on the other flows make it seem like you can upgrade. Then you go add credit card and years cap out at 23….you hate money.
  21. [R16] Fly Delta 1/5 · US We’re sorry - please try again later: Been trying to book a return flight for about a month. App never allows me past “Find Flights” button. I have other airlines to check as well as the delta website but the app has been useless.
  22. [R58] Fly Delta 1/5 · US Does not save AMEX: Suddenly every time I purchase a ticket I have to entire ALL my credit card info, including address that does not auto populate. At the end of the transaction it asks if you want to save the card for future use, but it never does. Next time I buy a ticket it asks me to add a card even though there is one saved in my wallet.
