The departure time for our Norwegian Air flight form London Gatwick to Oakland CA was advanced by 10 minutes. CheapOair had our email addresses and could have notified us of this change. We arrived 1 hour and 15 minutes before the flight time only to learn that the flight was closed out and that the next flight was 4 days later!
We spent $4,600 on new flights, but Cheap0air wants to close our file and keep the $1,500 we paid them for this flight for which we were denied boarding, because this was a "minor schedule change," so they aren't responsible for letting us know about the time change.
