Punctual flights but slow deplaning.

8.0 Very good

Nesrin, Feb 2026

Deplaning! What is up with the deplaning? It is mind blowingly slow. All four flights, the same issue. People waiting until the last minute to get their carryons. No one even gets up until the aisle ahead of them is clear. How frustrating. Flight attendants don’t seem to be bothered because they watch rather than encourage people to hurry up. Almost missed my connection because it took half an hour to leave from seat 15C!
