Which means you’re on an ex-UK aircraft or a refitted ex-AI one. In any case, I don’t really think there are that many non-refitted ex-AI A320neos left anymore.

with the terminal toss-up in DEL, how does the fly early options work for Air India or Indigo?

Do I go to the Terminal of Original Flight Departure and ask to be moved to a earlier flight (which might depart from a different Terminal) or check with Ticketing offices in the terminal of the new flight I want to move to?

I'm curious about CISF as they may not let in passengers departing from a different terminal? :confused:

How about connecting flights on same PNR (International to Domestic) - if I want to move to a earlier domestic flight after arriving from a International flight?

Probably best to call the airline, shift to a different flight and then proceed to the correct terminal.

You can access ticketing in T3 without entering the terminal.

Yes. usually its a Zoo with folks trying to get rebooking for cancelled / delayed flights. I'm also not sure if they process Standbys. in the past the checkin counter folks are able to move up the flight, take in bags and issue BPs at one go.

Can anyone recommend a good travel sim card for the US and Europe? I am basically looking for data only.

International roaming on my Airtel number is an option but I need to get sims for my kids as well for our summer trip so just wanted to check what options there are. I used Matrix once many years ago and wasn't too impressed with them.

I use Maya and Saily all over the world, both are great and super easy to setup.

I used Orange a couple of years ago in Europe and it worked well.
