KIN - MIA

We were to land in Miami sometime after 3pm but couldn’t due to bad weather, we flew around for 2 hrs until we had to land in Forth Myers to refuel, we had to sit another 2 hrs at Forth Myers until given the clearance to refuel, we were hungry, thirsty and frustrated at that point. All the had on the flight to offer was a small plastic glass of water and a pack of biscoff, I requested a cup of tea and was told none was there. We were basically at another airport and not one of the staff could consider that the passengers might be hungry or thirsty being on a plane for around 8 hrs, which you weren’t prepared for, at least find some hot water on board.
