1. [R9] 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. [R39] 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 It has the most accurate flight information, so I don’t have to read the possibly outdated flight boards at the airport.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
3. [R74] 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
4. [R107] 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.
5. [R127] 4/5 · US Add baggage info to upgrading at check in, please: The app is amazing for routing you through unfamiliar airports-you get a turn-by-turn navigation as though you were on Google Maps! Room for improvement: 1) Receipts for incidentals & baggage-please make these accessible in the app. The “receipt” that is accessible doesn’t show how the item was paid for and misses important documentation require
6. [R166] 5/5 · US Lilia: Thank you so very much for putting such a great technology in place that check in process is so easy even from international airports
7. [R260] 5/5 · GB Check in: Super easy and swift check in.
8. [R1] 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…
9. [R3] 1/5 · US Does not work: Cannot login in the app or create an account. The website works fine but the app is broken.
10. [R13] 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
11. [R100] 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.
12. [R4] 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.
13. [R6] 1/5 · US Errors with every tap: Every single time I tap on any buttons within the all, I get an error. This happens after multiple updates and even new phones. I usually have to go to the website and login from the desktop to be able to do what I need.
14. [R8] 1/5 · US Buggy: Flight purchase failed three times and said “invalid last name” even though everything was clearly correct. Two minutes later it asked me to check in for my flight which had apparently been purchased successfully, despite the errors. Not ok.
15. [R33] 2/5 · US Delta doesn’t want you to buy tickets: I hate to say this but I am no longer allowed to purchase tickets without receiving annoying messages to “correct items” prior to check out. Except the app will not let you actually see what information is lacking so you can edit and complete purchase. You cannot be logged into your own skymiles account. Too many bugs. The only way it goes through is if you a
16. [R5] 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
17. [R95] 3/5 · US Used to be helpful, but now bugs: I used to use this app to track all my trips, but for the past few weeks it won’t show my trips. I have to type in my confirmation number in the My Trips section for it to fetch anything - before it would update automatically based on my account. It still does on web browser, just not on the app. Fix this please 🥹
18. [R191] 3/5 · US Bug fixes needed: App is smooth but doesn’t update in real time. SkyMiles and MQDs consistently shows inaccurate information. Pending MQDs doesn’t show real time. Needs to be fixed.
19. [R200] 3/5 · US Sky Miles do not update correctly.: I’ve been using (and liking) this app forever. But now the Sky Miles total does not update. It seems stuck. The Dollars spent and lifetime miles update fine. I reported this to Delta and sent them screen shots from the app and from the web page, demonstrating the discrepancy. They basically shrugged and said it must be me???? I restarted the app; then restarted
20. [R17] 2/5 · US Doesn’t work with VPN: If I have my VPN turned on, the app constantly gives me errors, even when I’m doing things that should not require my location like adding a trip to my account. I don’t know why Delta needs to scrape more data from me, but I don’t like it.
21. [R21] 1/5 · US Unusable. Disappointed with Delta!: I downloaded the mobile app because it has become literally impossible to use Delta’s website on my laptop (VPN on = the whole site bricks me out with “access denied”, VPN off = I reach the home page, but every search immediately pulls error codes and kicks me straight back to the home page). I have tried multiple times, and several days apart. The app doesn’t w
22. [R27] 3/5 · US Dark mode: Add dark mode in the app
23. [R324] 3/5 · GB Profile update: Just loaded the app and tried to add phone number to my profile. It needs seven digits but my UK cellphone number is only six digits. How can I get the right number in?
24. [R353] 3/5 · GB Re-inputting passport information: Good app, with the exception of having to repeatedly input already saved data - passport information and name...
25. [R407] 3/5 · GB Nearly a great app..: I like this app, but I cannot enter a UK address ( needs province and nothing works) so it is now useless
26. [R448] 3/5 · CA Poor passport scanner: Passport scanner is not working on multiple occasions
27. [R41] 4/5 · US Boarding status?: The app does not provide current boarding status, including the zone that is actively being boarded
28. [R19] 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.
29. [R36] 1/5 · US Lacking in reliability, intuition: Checking baggage, for example… putting in CC info and their form checking says invalid, but really the number in the box matches. And the app accepted this information 1 week prior for a different flight checkin. Intuition: app should be easy for my spouse to navigate to find information - it is not. Other airlines apps - SW, AA - were not. I don’t think spouse u
30. [R102] 4/5 · US Widgets still don’t work consistently: Never have worked properly. Occasionally they’ll work and display my trip, but then disappear after you tap on it. You should hire the people that wrote the United app, it’s very good. I’ve never used an app before that didn’t have working widgets.
31. [R156] 3/5 · US Update: I’ve used this appSeveral times because I don’t have a new phone. It won’t let me update. I think you need to fix your app for people with older phones can use it and not have to go buy a new phone just to use your app. It’s kind of disappointing.
32. [R211] 3/5 · US Useful for newish phones: I used the Delta app for several trips and never experienced any issues. However, with their updates and my old phone (iPhone 8), I no longer have an iOS software that is compatible with the app. Even if I download the old version, I cannot log in or access my boarding passes, leaving me to retrieve my trip information via the internet. Not a major problem if the majori
33. [R31] 1/5 · US 1 hour login: I’ve been trying to login for one hour reset passwords username nothing works. It’s got Miles nothing.
34. [R16] 1/5 · US Horrible app: After 35 years in software I know a bad app when I see one. This one is terrible. Was very good in 2019 when I last used it. Does not lead you through standard navigation steps to book a flight. Selection texts all over the place. Then at the end, the pay by credit card button not active. No explanation why! Ended up going through phone reservations which was its own nightmare.
35. [R12] 2/5 · US Known Travelers Number Issue: I added my Known Travelers number in the Delta app but it didn’t update the Delta website accordingly. I now must go to the front desk to correct my boarding pass.
36. [R104] 4/5 · US Refresh: I find that I have to uninstall it and reinstall in order for it to refresh MQD and current mileage. When I pull down to refresh, it will not refresh.
37. [R110] 3/5 · US Code Share: The app is mostly good but have no idea why you can’t check in on a connecting international flight that is a code share brand. If you book on delta, you should be able to check in without any problem and certainly not going to another app for check in
38. [R333] 3/5 · GB How many times do I need to scroll countries: Works if you are US, but try UK. I assume there are easier ways to collect this info
39. [R164] 5/5 · US Ok, but not great.: App does well with boarding passes and flight updates. Tracking bags is hit or miss. Sometimes bag tag is already connected to app, other times you have to scan the code each time you want to track. Apple watch support is awful. Hardly ever connects. Unrefined and incomplete would be best description.
