  1. [R1] JetBlue 1/5 · US Misleading: This JetBlue app is terrible, especially for people using the JetBlue Key Blue credit card. You spend thousands of dollars earning points, only to open the app and realize most flights are blacked out or unavailable to book with points. What’s the point of pushing a rewards credit card if the rewards are nearly impossible to use? The whole experience feels misleading and extremely frus
  2. [R6] 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.
  3. [R10] JetBlue 1/5 · US Unreliable and the reason I’ avoiding JetBlue in the future as a result: App started having tons of issues displaying my boarding pass while going through customs/tsa (i had cell and internet connection) and made what should have been a normal flying experience extremely stressful. This was our first time with Jet Blue and due to their app it will likely be our last
  4. [R18] JetBlue 3/5 · US Where is Best Fare Finder: Why is best fare finder missing on the app.
  5. [R11] JetBlue 5/5 · US Jet blue !!: I love jet blue but the app has been very slow lately and I’m just not feeling the same love for the app as much as l love jet blue
  6. [R12] JetBlue 3/5 · US Does what it needs to, but buggy: Usual airline app. View trips, book trips, “featured content” ads. Nothing special. Gets the job done. There’s a bug where it always shows one notification badge on the app icon, and when you tap on the envelope on the main screen, the app crashes.
  7. [R16] JetBlue 2/5 · US Extremely buggy 2026-06-24: Sign with 2FA causes screen loop. Name field when booking a flight is uneditable.
  8. [R20] JetBlue 4/5 · US App stopped accepting two factor code: Need help. Keyboard doesn’t appear to insert code
  9. [R27] JetBlue 3/5 · US Mixed messages re delayed flight and gate: My flight has been delayed twice in the past 6 hours (and may do so again; who knows?) and my gate has changed. First delay notification and just-now gate change came via email. But second delay came via text. I signed up for text, I don’t check email often. Confusing. And differences between what app and website say. Makes me very anxious.
  10. [R32] JetBlue 1/5 · US App out of sync: The ticket in the JetBlue app shows one gate and the JetBlue status notification says a different gate I had to find an agent to see which was correct She tried to tell me it was the ticket in my wallet Which it wasn’t the one reporting the wrong gate and in fact the wallet and the ticket on the JetBlue app had the correct gate It was the JetBlue notification that was wrong. The
  11. [R41] JetBlue 3/5 · US Slow, drains battery: The app is quite slow compared to other carriers’ apps. My phone keeps giving me warnings that the app notifications are draining the battery. Seems odd to have an airport map that doesn’t label the gates.
  12. [R62] 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!!!!
  13. [R4] JetBlue 1/5 · US Broken seatback screen: The online customer service for Jetblue is useless for reporting broken equipment on flights. Don't bother using it for that.
  14. [R21] JetBlue 3/5 · US Credit: We had 3 flights cancelled due to Hernando. 2 Jet Blue and 1 Frontier. We never got to Florida and had to cancel our flight home due to this storm. Why can we only get a travel credit for our trip home and not a refund. This was all storm related.
  15. [R39] JetBlue 3/5 · US Travel bank: Book a trip three months in advance. Made a mistake lost almost $1000 in one day. They put the money in travel bank account which expires after one year and is virtually impossible to access. Feels scam.
  16. [R70] 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…
  17. [R15] JetBlue 3/5 · US Forced to log in again when searching flights - poor user experience: Latest app update forces you to log in every single time you want to search for flights - even if you check off save my info. I’m already logged into the app so why do I need to log in when searching for flights! This is time consuming and frustrating. It’s now better to use your website than your app. Please consider reverting
  18. [R23] JetBlue 4/5 · US Booking Search Results: the update is not easy on the eyes. the old format was much easier to view multiple options at once, this is too basic. you can’t even filter or sort!
  19. [R45] JetBlue 3/5 · US Used to be so user friendly but not anymore!: JetBlue has just updated its app to only show the exact date (not even the day of the week) in the search results. Terrible search results and so difficult now to navigate. What happened???
  20. [R46] JetBlue 1/5 · US awful sign in awful booking: It’s just a web view not an actual app experience
  21. [R30] JetBlue 1/5 · US Worst app ever: Horrific, I can literally never book a trip . I lose on money or points . It Never lets you seamlessly book 🙄🙄🙄🙄 get a different contractor for your app. They suck
  22. [R61] Fly Delta 1/5 · US Problems Booking Flights: The app keeps getting an error when trying to book a flight. That’s the whole point of the app
  23. [R22] JetBlue 1/5 · US Can’t add to wallet: Can’t add to wallet
  24. [R49] JetBlue 3/5 · US Missing apple wallet on lock screen: The apple wallet boarding passes used to come up on my lock screen automatically, but no longer do. Now it wants me to just get the boarding pass in the app, but that requires me to unlock my phone and have cell service. Bring back automatically bringing the passes up on the lock screen.
  25. [R99] 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.
  26. [R35] JetBlue 3/5 · US When it works, it’s great!: When the app works, it’s great! Booking, managing, customer support, all excellent! My issue is the app seems to get updates often which is great but I then have to constantly re-log in. Many times, I go through a multi-step sign in for security reasons (again, great for privacy) and after submitting codes to log in, it brings me right back to the log in screen. I go th
  27. [R56] JetBlue 1/5 · US Sign-in Issue: Zero stars! Unable to login. Account verification email received with code and entered, yet system still defaults back to original sign-in screen to repeat process.
  28. [R69] Fly Delta 3/5 · US Login process sucks: The login on the app barely works at first
