I live close to MDT, about halfway between IAD and EWR. JFK is possible, but entails a more exhausting drive. I have 67,000 miles with CO, with no real rush to use them, and some (less) miles with UA.
I would like to visit Bangladesh (DAC) some day.
Here are the options I have found, if I went this May for instance:
Use Qatar all the way, from IAD, changing in Doha. This sounds like the easiest option... but the transit time in Doha on the return is 20 hours! $1,400. Total time 23h to and 43h back.
Use Etihad all the way from JFK. The connections in AUH are on the skimpy side (90 minutes). $1,200. Total time 19h to and 21h back. Plus the tough drive.
Use CO from EWR to BOM or to DEL ($1,000), then connect to an Indian Airline, which sounds more fraught that sticking with one carrier.
Another option is to shoot for Kolkata, then take the very interesting train between CCU and DAC.
Since I can only take 10 days off from work, is this a crazy idea altogether, and better go to Suriname (my other current fantasy)?
