This is wrong for 99% of countries. See the post of Grouchy for the requirements applicable to transits in AMS coming from most countries.

Per Grouchy's post above, for ATL-AMS-DXB, I don't need a 4 hour test. 72 Hours RT-PCR is aedeqate

So you did have (and needed) a negative test to transit in AMS. If you didn�t show it to Delta you wouldn�t have been allowed on that plane.

Correct.
My post was responding to HohoGap's post who said no test was required for transiting in AMS, which is wrong except coming from a handful number of countries (and not including USA where he/she was coming from).

My Dad flew ORD-AMS-SVO (Russia) on KLM last Sunday and the only thing he needed to show was negative result from PCR test taken within 72 hours of arrival into AMS.

Help! I am a US citizen flying LAX-AMS-BCN on KLM, and I cannot figure out if I need a Covid test before departing LAX. I have looked at the Dutch government site, the KLM site, the Traveldoc site with the IATA rules, and even the KLM twitter feed. There is so much contradictory information out there.

Has anyone flown from the US to a Schengen country via Schiphol since June 1 when they changed the rules? Were you asked for test results? Spain does not require a test, so I would really prefer not to pay for a test if it is unneccesary.

Thanks!

The rule changes recently and the NL government site is pretty clear : no more test needed when transiting in AMS.

The relavant part for you is at the bottom of the page

There's a big difference between requirements to board and requirements on arrival.

Question is how much OP wants to risk it....

I have the same question as the OP. KLM sent me a message saying that I need a COVID test to fly to AMS even though I am only transferring. My journey is LHR-AMS-CPH and I know the UK is not on the safe list but neither is the US.

"The Dutch government requires you to show a negative COVID-19 NAAT(PCR test) result and a rapid antigen test. Having only a NAAT(PCR) test is allowed, if you have a transfer flight in AMS or if the NAAT(PCR) test is not older than 24h before departure."

I have sent a message to the Dutch Ministry of Foreign Affairs and they also tell me this:-

"You need a negative NAAT test outcome no older than 72 hours at the expected time of arrival in the Netherlands."

So I wonder if the change from the 1st June is the requirement for the two tests (one to arrive in AMS and the second rapid test to transfer) and now you can just have one? This is how I read it from the Schiphol website:

"Transfer passengers exempt from test requirement

As of 1 June, transfer passengers travelling via Schiphol are exempt from the negative test requirement. If you are staying at Schiphol during your transfer, you do not need a new negative COVID-19 test result. Your test result remains valid throughout your transfer, including any potential delays. "


Unfortunately reading the government.nl page on the rules for changing planes seems to be only half the story and needs to be read in conjunction with the general rule for arriving in the Netherlands, at least this is my conclusion.

Traveldocs did not say that I need a COVID test to enter or transit the Netherlands to add to my confusion.

I arrived AMS from the US on Monday 7 June on my way to another Schengen country without a test (since AMS transfer didn't require one, and my destination Schengen country didn't either for fully vaccinated pax). On arrival in AMS we were met by Dutch personnel at the jetway door asking to check our PCR tests. I told him that I didn't need one for transfer and showed him my onward boarding pass. His response was "you are right, you don't need one for transfer, but most passengers have one anyway so we are asking to see them..." (??!?)...and then I was allowed to go on my merry way....quite strange actually....

Edit: I just checked the Dutch government website again, and under the section "Negative Covid-19 Test result: rules when changing planes" and it says:

....If you start your journey in a high-risk area or country and change planes in the Netherlands,
- you do not need to show a negative NAAT (PCR) test result or rapid test result on arrival in the Netherlands
- a transfer is when you change planes and continue your journey within a few hours, and in any case within 1 day without leaving the airport where you transfer...

Thats what I read on the government website as well but then KLM sent me messages telling me I needed to have a test for transferring so I sent a message to the Ministry of Foreign Affairs outlining my itinerary and they told me I need one. Could both of them be wrong? Why would they tell me I need it if I do not, maybe they are as confused as I am. I do not want to pay for a PCR test when it is not needed esp as only an antigen test is needed for Denmark plus they have mandatory test on arrival.

Well I resent my question to the Ministry of Foreign Affairs earlier this morning and I got a different reply from a different person, they said no test is required to transfer in AMS. So I will not get a PCR test and will rock up to the airport and see what happens. I will just have an antigen test for DK.

Thanks all. This is the response I received from KLM: "Hi! Some local authorities demand that passengers must be able to show a negative COVID-19 PCR test result. These demands are not imposed by KLM, but by the local authorities. Therefore, I strongly recommend that you always contact the local authorities."

It seems that no one actually knows. It is encouraging that ClipperDelta was ok without a test. Not sure what I will do, other than hope there is more clarity before I fly.

I'm surprised that there's no difference between a nonSchengen to nonSchengen transit (airside connection on one ticket) versus a transit where one would enter Schengen at AMS. In the latter case, there would be little to prevent someone without checked bags from simply leaving the airport and spending some time as a tourist in the Netherlands unless the authorities have recently installed some additional checkpoints (perhaps around customs). Maybe I don't understand where passengers' COVID-19 documents are being checked at AMS.

It seems clear that no test is required for non-Schengen to non-Schengen. For non-Schengen to Schengen, there is a paper quarantine form that you are required to fill out where you pinkie-swear not to leave the airport. A big part of my angst is that I don't quite believe they would really do this.
