I flew from the US to Delhi for a vacation, but must have left my keys on the flight itself. I am an elite member if it matters.

2 Questions:
1) I'll fill out their online lost & found form - any recommendations on what else I should do? Contact all the airports I was at if they have lost and found instructions online?

2) Any idea if there is a place I can ship an extra set of keys? (I have an extra set with someone in another state - I'm going to Ohio) My car is parked in the long term parking at the airport and I don't have keys to get to it. I can't even take a cab to my apartment to get my keys, because yet again, I need keys to enter the building and receive packages. I'm on the line seeing if I can ship it to the Continental desk, but odds are looking slim. What should I do?

In addition, I just moved to a new city 2 days before flying out and the few people I do know are also out of town on their own trips.
