Figured this was the best place to post this question. Called EY and got an incompetent answer (no surprise).

We are flying IAD > AUH > DEL and transiting DEL to fly to PBH. From what I can gather transiting is easy enough at DEL, however this is the question.

To fly from IAD > DEL, which we have done, we needed a visa last time to board the flight.

However, we do NOT need a visa since we are only transiting but I do not want to be denied boarding.

Will I be able to board this flight without a visa?

Advice?!?
