Air Travel in India

We took our first domestic flight in India and learned that there are some differences flying in India vs. the U.S.

1. You need a ticket or receipt to even enter the airport. (Airlines have booths outside).
2. You take your checked bags through security before checking the bags in.
3. At smaller airports, you don't go through security until it's close to boarding time.
4. Women and men are screened separately (women have a private cubicle area).
5. Airports are much smaller than in the US.
6. When you get on the plane, an officer checks to make sure your carry-on has an airline tag that was stamped when it went through security.
7. Most importantly: the people arriving and departing never mix (in many airports).  If you have transfer, you have to go through security again.  This was a surprise when we made a connection in Delhi.
