Our flight, which was supposed to take off at 5:30 PM, was delayed for over 4 hours. It's not necessary to mention the airline because delays are common. And the policy I heard directly from the staff at this lounge is that they remain open until the last flight. We felt lucky to spend time in this lounge while waiting for the plane to board because they were supposed to be closed. Not only that, they also refilled food and drinks, including plates and utensils. The bathroom and prayer room were also clean. Highly recommended for those who are forced to use an airline that often delays. Good Job Concorde.
