  1. [R2] Amex 5/5 · US Excellent: This is by far the best banking app. It has the cleanest interface and the most responsive staff.
  2. [R4] Amex 1/5 · US Control was taken away!!!: Even though the app gives users the option to control secondary authentication, and I chose not to enable it, American Express overrides that choice and forces secondary authentication anyway. That is unacceptable!!
  3. [R16] Amex 1/5 · US Why change?: This was much easier and cleaner looking prior to this way now you don’t know what’s paid or not, simplify it for idiots like me! This app is awful
  4. [R18] Amex 1/5 · US Let’s find a way to mess up a good app…: Horrible update. Used to be able to see what bill needed to be paid. Now it’s stupid icons and you have to open each transaction.
  5. [R1] Amex 1/5 · US Trying to resolve a disputed claim: The CS experience awful. You can only text them not knowing if you have reached a real person. You can’t talk with anyone in the the department that handles the claims. I sent a fax and asked if it was received and was told they have no way of reaching that department.
  6. [R6] Amex 3/5 · US Does not provide customer protection like before: Amex have the best customer protection and customer service is bar none about 5 years ago , amex does not provide customer protection as it used to
  7. [R7] Amex 1/5 · US American Express Keeps Your Refund: Beware of Missing Money: I’ve had a very disappointing experience with American Express. Whenever I purchase items using my American Express card and later return the goods, the refund is supposed to go back to my card. However, American Express never returns the money, and I have to chase them down to get it. Even though the store has fully refunded me, it seem
  8. [R8] Amex 5/5 · US The best customer service: Love Amex! The difference in customer service is night and day compared to any other credit card Hands down the best I have several Amex cards but just received my business cards. Every expense from every employee is now dialed for easy accounting. Amex will always be the card available
  9. [R11] Amex 5/5 · US Best card out there: So many points earned is paying our vacations great card to have.
  10. [R15] Amex 3/5 · US Good if you travel. And are ok spending time optimizing perks: Could be more transparency with when/how things are reimbursed that are listed as credits. For example, Clear was supposedly included, but now I am paying for it. I really hate Clear. And they put enough red tape that it’s too difficult to undo. Was told to dispute it by Amex. On top of that the card itself costs almost 1k per year. An
  11. [R17] Amex 5/5 · US Love it: No issue, safe to use, just what I needed for travel. Perks are a plus!

  14. [R36] Amex 1/5 · US Stupid and aggressive rating upsell: Why do you ask for review every single time when I open the app? Who’s the growth PM? Super bad user experience
  15. [R43] Amex 5/5 · US Service: Seamless. Easy to browse, pay, fast
  16. [R10] Amex 1/5 · US Bad card to use for business: I used love American Express Platinum business card and used it for most of my business use. But for last 2 years this card become one of the worst cards . High annual fee and we can’t even use it as needed . I will close this account as soon I have paid off the balance .
  17. [R28] Amex 1/5 · US Annual increase in membership fees and change of credit limit: The “perks” associated with having the card just is not worth the membership fee. Also, they will change your credit limit at anytime according to your relationship with other creditors with no warnings. There are so many other options out there than this card. It has truly changed over the years. Not worth it!
  18. [R61] United Airlines 2/5 · US slow: slowest app I’ve ever used. always buffering regardless of my cell service/wifi connection.
  19. [R77] United Airlines 5/5 · US The best self check in: United provides a super easy self check in, flight change or cancellation and any other service you may need. Love this Airline and their App!
  20. [R85] United Airlines 1/5 · US Check-in never works day before: It’s stressful that you can only check-in a few hours before the flight. Especially when yo have meetings to get to and no time to check-in hours before your flight.
  21. [R91] United Airlines 1/5 · US App extremely buggy: Long time user and frequent flyer on United. The app no longer works for my wife or I. Check in is virtually impossible, and simple tasks like choosing seats often take many minutes of waiting if it works at all.
  22. [R70] United Airlines 1/5 · US Checking bags: I get a free checked bag for me and my husband and it keeps charging me $50 each.
  23. [R76] United Airlines 1/5 · US Overpriced: Since regulators and unions killed Spirit, the tickets on United became twice as expensive Shame on you
  24. [R82] United Airlines 1/5 · US Carry-on: For as expensive as United flights are, not being allowed a carry-on is insane
  25. [R92] United Airlines 5/5 · US A Teacher: I miss Spirit airlines. I dined up for United credit card to earn a rebate of $400 but the airline ticket price was so expensive that even the rebate did not make a significant difference. I will probably cancel that car ASAP. I didn’t even approve a seat request and I think I was even charged for something I did not request 😭
