The worst airline I have ever flown I can’t even believe that this is considered a star alliance member. They gave me no control to change my tickets in person at the desk, nor via phone through the customer service. Basically, even though the flight was already paid for and I could change it I couldn’t do it through them because it was booked through a different agency like Priceline. I’ve never met an airline in which this is the case. If you’re rendering the service in the US, you are required to facilite the service provided otherwise it is fraud. I ended up waiting on hold for about 45 minutes before reaching a customer service representative and then they told me that they couldn’t do anything for me even after the third-party agency told me to directly call Nippon. This is with a refundable ticket. I was unable to change my flight through Nippon with a refundable ticket. Therefore I decided to just rebook a new flight and I’m still unable to get my refund from Nippon. The flight was $790 to change the flight and I took a total loss of $2500 on the first class ticket. My company will never fly this again and I surely won’t, please be careful you have been warned. My team is prepared to file a class action lawsuit for failing to provide service for my ticket and having the staff tell me they are unable to do anything. Will keep you updated!
