We have an early morning flight to Paro in Bhutan from Delhi. We will have arrived in Delhi about 36 hours earlier and plan to stay at the Radisson close to the airport for 2 nights (though whether arriving after a flight landing at 01.25 on a Friday morning then departing on a Saturday at 07.30 is really a 2 night stay is debatable...).

Can anyone give me any tips for the departure of the Paro flight so that we don't have to rush around the airport on arrival at 01.25 checking what we need to do for departure?

I assume it goes from the International terminal (sounds obvious but just checking!). Is there a particular door we should try to aim for to enter the terminal? (I noticed on other threads that some doors might be less congested).

Also how much time should we allow for check in? The Paro flight is on quite a small plane (a Dash I think) so not many passengers but I guess the same security queues as the long-haul flights.

Thanks in advance for any advice.

Be there 3h before the flight at the international terminal. There is no major intl flight departing at that time, so doors should not be an issue.

The airport will not be as busy as during the rush hour at night so getting to the airport at least 2 hours before departure should be fine. Not much to do in the departures area, a few shops and a couple of fast food outlets (Subway). The security should be fine - make sure to get a tag for your carry on bags so it can get stamped at the security check point. You'll also have to go through immigration so have your forms filled out.

I think Druk Air operates an A319 on this route via KTM. Try to get a seat on the left side (Seats A-C) for great views of the Himalayas if the weather permits.
Have a great time in Bhutan.
