time in customs at Gatwick

If it is all one ticket, you are just in-transit in London. You would not go through immigration and custom since you are not entering G Britain. You might have to go through security but should be OK.

It's two different airlines and two different tickets. We are flying into UK on Easy Jet and flying to US on Norweigan Air.

With two different tickets, there's NO WAY I would try this. If this route is your only option, fly into Gatwick the night before, and spend the night nearby. With a 9:55 AM departure back to the US, you will want to be getting to Gatwick around 7 AM.

Given that you will have lines at passport control (customs should be a walk through unless you have purchases to declare to the British gov't) and the very real chance that your inbound from Venice could be late, you will very likely miss your Norwegian Airline flight and will be forced to buy new one-way transatlantic tickets. Thus follow what Harold advised.

Agree -- with two separate tickets -- too much risk. You will have to go through G Britain immigration and customs (although customs is a non-issue for time other than walking through.) Then you will go through security again, AND exit immigration for G Britain. Plus you may have a problem with the cut off time for check-in for N air. It is possible that the cut off time for check could be 9:10am. That is common in Europe. So might only have an hour. Too much risk.

Once again I'll write it....there is no exit immigration in the UK.

That is too tight. We flew into Gatwick last week from Naples. The lines at the Border Patrol aka /passport control aka /customs took almost an hour as folks had to fill out landing cards that multiple airlines that arrived simultaneously forgot or did not pass out on board.

Looks like the easyjet flight goes to the north terminal at LGW. I was unable to to figure out where your LGW-FLL flight departs from

The LGW site recommends 60 minutes for same terminal changes and 90 minutes 'minimum', for different arrival/departure terminals.

If you have already bought the tickets you can a) hope for the best or b) buy new tickets for VCE-LGW to get there earlier

Theoretically it is possible, but there is no room for anything but Swiss watch precision among all the factors.

Not something I would contemplate

Thanks for all the helpful comments and the link. I appreciate it. We will fly in the night before and find a cheap place to stay near Gatwick so we can catch our flight back to the U.S.

Or you could buy a travel insurance policy that covers missed connections. We are doing almost the exact same trip as you, except Chicago instead of Florida. Norwegian Air for the transatlantic part, then Easy Jet for the Italy to/from London part. We only have an hour layover in London on the way to Venice and I'm pretty much certain we will miss it. Travel Guard insurance has served me well in the past when I have had missed connections.

Flying in the night before will also make you happier when you leave Venice. If your original plan was that Easyjet which arrives at 8:05 it will leave at 6:50 from Venice meaning a middle of the night checkout. yukk. It seems that you are losing in Venice but you will actually feel better when all is done.

I flew into Gatwick yesterday morning about 10 AM. The immigration line for U.S passport holders snaked around the immigration hall and up the ramp. I don't think onow how long the wait was as I didn't, have to stand on that line.

I flew both Norwegian and EasyJet. Easy Jet is in the North terminal and Norwegian is in the South. There is a Premiere Inn next to the North Terminal.
