Venice to US via AMS, is 1 hour layover too short?

Single ticket from the airline or do it yourself linkage?

Will be single ticket via airline.

I’d choose the later flight from AMS
KLM is a nice airline too

Schiphol airport (AMS) is huge but a very efficient airport. I like flying through it. Personally, I would take the one with a 1 hour layover if there's a later flight home from AMS after the original - if booked all on one ticket and you are late and miss the connection, they'll put you on the next flight anyway. Might as well try to make it on the early one - you'll get home 2.5 hours sooner at best or at the same time at worst.

The security line for US passengers transiting BACK to the USA via AMS can be HUGE! No, I wouldn't give it just an hour...unless you don't mind potentially missing your connection and having to be on a different flight.

There are minimum connect times which vary from airline to airline depending on a number of factors - there is no standard. International is usually about 90 minutes - but can be one hour to 3 hours. I think one hour is probably not enough time to make the connection, especially if there is a delay and if you are going through additional screening at AMS to US - customs. I just flew from Naples to CDG with a 2 hour layover and received notice from Delta that this was an invalid connect time. I called and learned that it was a valid connect time, but anything less than 2 hours would not be valid. My preference is to err on the side of caution - and hang out at the airport a bit longer, or not have to miss the flight if say, a lightening storm or weather delayed the flight from Venice.

I have flown through Amsterdam a handful of times. Only one of those times would an hour have been enough time to get to my flight - and that is because there was no line at the security checkpoint (you may or may not go through one, but assume you will). You don't say where you're flying from, but I come from the West Coast so usually have been on a 10 hour flight - I need a stretch and have a not-panicked situation for my next flight. The 3.5 hour layover may seem like a lot, but by the time you deplane (big planes = take longer), stretch your legs, have a coffee, find the transfer desk to get your boarding passes for the next flight, probably go through some kind of security, and find your gate, you're at a good 1.5 to 2 hours. I enjoyed the outdoor seating area (above pier D I think) and next to it an indoor "park" with fake trees and comfy chairs. The airport has a small outpost of the Rijksmuseum if you feel like getting your art on.

We DID make a Venice-AMS-SFO flight at AMS (Alitalia-KLM) with a similar connection time several years ago -- but I remember panicky rushing and arriving at the gate when they were almost finished boarding. Wouldn't pick that now!

I, too, would go with the 3.5. I'm not a risk taker when it comes to high stakes flights. If you have any delays in Venice (fog?) then you are toast.

What time does your flight leave Venice? Last time I flew from Italy thru AMS back to US the flight left the Italian airport at an ungodly early time (6A from Milan). I swore after that that next time I'd fly to AMS the day before instead of trying to get to the airport at that early hour.

Definitely take the 3.5 hour layover. AMS is nice. I would do anything to avoid CDG!!

Here's another vote for 3.5 hrs over 1 at AMS. FWIW, we had a 1.5 hour layover at AMS (KLM/Delta single ticket) and just barely made our flight to Rome. Unfortunately, our two checked bags did not. It was 23 hours before we got our bags, which really threw off the first two days. So if you're going to do a tight connection, do NOT check any bags.

"So if you're going to do a tight connection, do NOT check any bags."

Well, OP's asking about a flight heading back home to the US so presumably everything will be dirty, lol. Don't pack your car keys or your charger cords and check the rest.

So here's the thing. As it is one ticket, the airline will put you on the next available flight, which could be later in the day or the next day, etc. If you have to be home for some reason at a particular time, take the lengthier layover. However, if you don't have to be home right away, take the short layover. If you don't make the connection due to their lateness, etc., then the airline will put you up...that's my understanding. Someone correct me if I am wrong. There are advantages to having a free extra night or two. Just pack an overnight kit with all your important items, check the rest of your stash, and hope for a delay. Enjoy Amsterdam on the airline!

If it were me, I'd go with changing planes in AMS and taking the 3.5 hour layover. CDG can be a nightmare.

My reasoning is this: The first flight may be on time. It may be late. If it's late, the connection is in danger. Even if the first flight is on time, it takes time to disembark from the first plane. Then there are possible security checks. Then there's the fact that international flights usually start boarding earlier than domestic ones, so an hour layover really isn't even a full hour until the next flight starts boarding.

But I like to make my travel as relaxing (for me) as possible. I know that's not everyone's travel style.

I'd go with the 3.5 hours at AMS. Your risk of a late arrival is less from Venice than it would be from the US, but still an hour seems pretty risky even if the flight's on time.

Now if your next question is can you go into the city and look around during that layover, the answer would be no, not enough time for that. ;-)

EDIT: Another thought -- if you're like me and want to collapse at home after a long transatlantic flight, the later in the day you arrive the closer you'll be to a normal US bedtime, making the transition to home time easier.

Thanks All appreciate the feedback. So all booked, did the AMS flight with the 3+ hour layover. Guess better safe than sorry.
