Fast track service option at FCO airport

You are going to have to provide more information or a web address. Not sure why or how the immigration process and train could be tied together. Unless there has been major changes in the immigration process, you just walk through passage ways from the plane to immigration. No place to buy anything.

PS - Just found it on the Trenitalia web site. It is for going from Rome to Terminal 3 and refers to exit passport control. Has nothing to do with arriving in Rome and immigration (passport control). There are some changes being make in how international travel to the US is being handled. Before you have to go through processing in Terminal 5 but now Terminal 5 is being remodeled so departures are now handled through Terminal 3. It often was a zoo in Terminal 5 so it looks like you can buy a fast track through immigration for terminal 3. No experience with new system.

Frank, it looks like this is what Bill is talking about (scroll down to "Special Offers"). I'm not sure how it works.

Those links were very helpful, thanks. I was thinking the fast track might be something akin to the Global Traveler option we have in the USA. So far I'm not sure how well this particular Fast track service works as the details are a little sketchyon those sites. Whisking me from the gate to customs looks nice, but does it really get me through customs faster ?
I'll continue to look into it - Thanks

Why are you in such a hurry? Passport control takes seconds and lines are rarely long.
Customs is just a walk through the green line.
What takes long is waiting for luggage at the baggage claim.

For some reason I have the bad luck to get stranded for what seems like forever going through customs.....In Paris and Vienna in particular...although I guess it could have been jet lag kicking in.
It sounds like the process at FCO is not too bad.
Thanks !
