Amsterdam transfer time

As much as I love a short layover, I'd be a bit nervous with that AMS time. Paris is no picnic, but I'd be much more comfortable with that.
What month will this trip occur? Last summer was a nightmare, but in early spring or fall, I would be less worried.
The airlines are going to see you a "legal" connection time, but when I have been worried about making a connection, I always look at a map in advance and check to see when the next flight is just in case.

Wednesday October 11 is date of flights
What is a legal transfer?
My thinking is that Paris airport much more crazy so an extra hour may not be worth it
Thank you so much!

Also, Florence has a very small airport. You will probably find more options if you also look at flights from e.g. Pisa or Milan.

Currently the minimum legal transfer at AMS is 50 minutes, and 60 min at CDG, for this type of international connection.

"Legal" just means the airline has determined that you can realistically make the connection. It's a safer bet than booking two separate flights yourself. But flights can still be delayed.
AMS may be smaller, but it can be an absolute mess. In October, I'd take the chance with an hour though (would not in July or August).
Unless you'll get fired if you come home a day later, it's always worth it to me to have a more convenient schedule.

You should also make sure you have an extra Schengen day left in case of delays.

What is meant by having an extra S. day? Our trip is 13 days

then no worries--Schengen means you get 90 days.

Is there any security or passport check station we will need to go through during that hour layover when making that connection for our flight to Seattle?

I’m leaning towards keeping the AMS connection from Florence to avoid having to fly thru Paris

We have been to Italy three times in the last year and a half. Each time connecting in Amsterdam both ways. It's always much quicker than our experiences in Paris and London, but an hour might be tough.

I much prefer AMS to CDG. Yes, you will go thru passport control. I wouldn't worry too much about it right now. By October, your flights will probably get changed anyways. At least that's what I have experienced with Delta/KLM/AF (multiple flight cancellations/flight time changes). It all works out in the end.

AMS has a separate line for short connections.

Thank you David. Still looking for explanation of what is required of us during that hour? Any passport checks or lines, or do we simply need to find our gate for connecting flight?

Thanks Gail I needed to hear that this am!

Not sure why we would go through immigration leaving EU country for US. We will go thru customs in Seattle so I don’t understand what will be required of us when making connection from Florence in Amsterdam to our US flight?

Well who can explain that--but security is tight as ever, and shifting from an intra-European flight to the US flight will require time in a line, unfortunately. It's not a big deal.
In October, I really would not sweat it.

You’ll be exiting Schengen and going thru US passport control at AMS

Will having Global EntryPass make this quicker. I am still in the dark what this step in AMS will entail ?

Some changes have benefited the tourist, like the euro vs having to deal with many individual national currencies. The Schengen change does not benefit the tourist. In addition to the 90 day limit (whereas before Schengen you would get 30-90 days for EACH country), you can't get to the airport early to deal with the time required for passport control, it has to be done (on a connecting flight) in the connection time between flights. Basically you will be formally leaving Italy when changing planes at the airport in AMS. They will check your stay length and stamp you out of (most of ) Europe when walking between gates in AMS. Normally it takes no more than 10-15 minutes at AMS.

Global Entry will only be useful when you arrive in Seattle

We have navigated AMS with a 50 minute layover on multiple occasions. Just hustle through the airport and, once you get to passport control, let an airport staff member know about your short layover and they will usher you to the front of the line. I have heard horror stories about AMS but I have not personally experienced any of that. Good luck.

“ Not sure why we would go through immigration leaving EU country for US. ”
That’s simply what the rules are. You go thru passport control when you arrive in the Schengen Zone and you go again thru passport control when you leave the Schengen Zone.
Your flight from Italy will arrive in the Schengen zone of Schiphol Airport, your flight to the USA will depart from the Non-Schengen part of the airport. These two sides are separated from each other by passport control. When you arrive at Schiphol, you follow the signs to the gate your flight to the US departs from. When you follow these signs, you will automatically come across passport control. You show your passport so your departure from the Schengen zone is on record.

All replies are so appreciated!

At your departure point back to the US you go through immigration to make sure you leave - it's the record that you have departed. I would not be comfortable with a layover less then 90 minutes through AMS at this point. I'd be happy with 2 hours in Paris.

I connected from Florence through Amsterdam this past September.
AMS is a huge airport, and not terribly well signposted.
Two uniformed staff that I asked for directions to my next gate had no idea where to direct me.

I've flown out of Florence many times, and I would say about 30% of those flights were late leaving Florence.
So, one hour doesn't give you much time to make the next flight no matter where you are transferring.
I would try and find a flight that gives you at least two hours to reconnect.
