My experience was not satisfactory. The check-in and boarding counter process was extremely slow, which caused significant delays and frustration. In addition, I had pre-booked seats for myself and my wife through the app. However, when the boarding passes were issued, we were assigned different seats. My wife was assigned Seat 16, while I was assigned Seat 40. This was very disappointing, as we had specifically selected seats together when making our booking. Overall, the experience was frustrating, and I would appreciate an explanation as to why our pre-selected seats were not honored.
