Dude,

The price seems reasonable for the time of the year you're travelling. But, from Houston, there are shorter routes than u have for around the same pricing.

1. Houston >> Doha>> Kathmandu (with Qatar Airlines)

2. Houston>> Frankfurt>> Abu Dhabi>> Kathmandu (with Etihad)

There some other airlines with more direct routes than the one u have right now. Be sure to check all possible options - dont think there will be a that much price increase if u fly with Qatar or with Etihad in the above routes. These routes also have a fewer flight as well as transit time.

If you are travelling in ur current route, make sure with ur travel agent that u will be provided with a hotel (& ofcourse complimentary dinner & breakfast) in Abu Dhabi as all Etihad passengers are entitled to it with more than 12 hours of transit in Abu Dhabi. Some even get with a transit of 4 or 5 hours. So, be sure to check with ur agent & make him write a note in the system so that there wont be any hassble when u land in Abu Dhabi and claim ur complement.

Good Luck.
