I jumpseated DEL-EWR in February. I was not in uniform. I went to the United ticket counter on the side where you can get in without any document. I asked the gate agent I would like to list for the jumpseat. She took my crew ID, passport & OCI. She came back 10 minutes later with a printout. I didn't pay any taxes. I took the printout & got in the airport. There were several seats open that day so I got a seat right away once I checked in at the ticket counter. If the seat availability is tight they wait until 1 hour prior to release seats. I found the process hassle free. Hope this helps.
