I don't see many flights on the Bhutan airlines from KTM to Paro in late October.
Are the schedules for October loaded Yet?

Thanks

Ask the local agent you are working with - they all know the schedules. And, as you know, you are required to book through a local agent even if you use an out of country agent.

The heavily traveled routes to Paro are from Bangkok and Delhi (additional flights from Bangkok are sometimes added during the peak October festival season), so you won't find daily flights from Kathmandu.
If you go in October, you'll need to contact an agent early to get your flights and hotel booked.

Thanks to both of you. I find with more research, that the flight schedule to Paro is only loaded until October 25. The last few days of October etc. are not up yet.
Now I have to determine which tour operator in Bhutan to use.

Last year in the fall there was only one flight each way between Kathmandu and Paro on DrukAir. These were both morning departures. I expect the same will be true this year when the schedules are published.

Allow extra time since the flights are often cancelled due to weather conditions. When we were in Paro the airport was closed for several days. Weather looked good to us but I am sure they knew what the conditions over the mountains were. The views during the flight were amazing!!
