My experience was bad. First no one inform us we need to go 2 hours before, hence when arrive 1 hour b4 flight departure we were denied entry. There was no announcement in Al Reem Lounge nor specific directive given when check in or at lounge.

Ended up not only us but 6 to 8 passengers was reroute to United Airline flight. When in DC it took us merely 5 mins to line up & 2 mins to clear immigration.

I would prefer to clear in US instead
