Today I flew from the EU to the UK via Amsterdam airport (AMS). I was held momentarily for secondary screening at passport control (I have an EU passport). The officer explained that someone with my same first and last name and date of birth was recently banned from entering the Schengen area. He also said that I should expect to be sent to secondary screening virtually every time I pass through passport control, at least at AMS.
I have my flight back in two days and my connection time is 50 minutes, which is the tightest allowed connection time at AMS when crossing the Schengen border. I am afraid I will be held again and consequently miss my connection. According to this EU page, I would not be entitled to compensation.
You are not entitled to compensation if you miss your connecting flight due to delays at security checks or if you did not respect the boarding time of your flight at the airport of transfer.
What can I do to maximise my chances of making my connecting flight (which is the last of the day to my final destination)? Or, alternatively, to get rerouted by the airline (KLM)?
Is there anything I can say to the aircraft crew, the ground airport staff or the police officers, which will increase the likelihood of a positive outcome?
If it matters, I have gold status in Flying Blue.
Update. To answer questions received in comments & answers, I did not get anything written on my passport nor anywhere else. I also don't know the name of the supervising officer I spoke to.
I contacted KLM customer service, but it was not really helpful. They only stated that I can be rebooked on a next-day flight, but overnight accommodation is not supposed to be covered. They still encouraged me to keep the receipts and file a claim, although there is no guarantee that it will be accepted. (In fact, I think it's almost certain it will not, according to the rules.) I did not get any answer about what potential steps I can take to maximise the chances of making the connection.
My passport is from a country which is both in the EU and the Schengen area. Later on, I will try to address the problem of differentiating myself from my "evil doppelganger" and I will probably ask a separate question about it.
My flights back are tomorrow, so I will soon be able to update again with the result of this "natural experiment" on connection times at Amsterdam airport.
Update 2: My incoming flight was on time, but I was not able to arrange anything with KLM that could ensure a faster access to the passport control area.
Upon arriving to said area, the access to the automatic machines was closed and everyone was queuing for the manned gates. I made an airport staff member aware of my tight connection and they let me through the automatic machines (why they were not available to everyone is a mystery to me). The machine, as expected, refused my passport and alerted an agent who came and picked me up. I explained the situation and was escorted to secondary screening. The procedure was fast (although my impression was that it was slower than the first time) and, although by a little margin, I made it to the gate and could catch my connection.
Long story short, a 50-minute connection time in Amsterdam is viable, provided that the incoming flight lands on time and that no unforeseen event happens. It is even feasible in case of minor disturbances. However, it is definitely important to ask airport staff to be let through the fast line because queues can be long.
