Bandarban Tour and Dhaka-Katmandu flights

Has anyone taken Guide Tours 3night/3day Bandarban trip using train/bus/car? We are thinking of doing it but would like to hear if anyone has experience of it.
Getting excited as we will soon be in Bangladesh
Also can someone tell me the best flights to use from Dhaka to Katmandu?

Thank you

If the tour company is Guide Tours I will highly recommend to take this trip. They are the best in this region. They have some nice cottages in the hills of Bandarban. I stayed in that cottages. Awasome experience.

I haven't personally been there, but quite a few friends from far and wide, praised the Guide Tours regarding their trips there. You'd be fine, I guess!

Regarding flights between Dhaka and Kathmandu, it's easy, just avoid Biman and opt for anything else, albeit it's such a short haul flight...Biman is to be avoided at all cost, unless they improve their service!

Thanks so much for your answers
