This question comes immediately after reading this hot network question.
I have currently no reason to think, neither I have ever checked, to be I am on US No-Fly list, which, according to the linked question, applies also to flights transiting above the United States.
I am currently planning an expensive trip to Canada from Europe, but haven't yet purchased the tickets. Actually, I also know that Canada and Unites States share ESTA/eTA information so it might not necessarily be any sort of problem with the trip.
Since the trip is particularly expensive for me, I would avoid any sort of bureaucratic problem that may lead to denied boarding or rejection at the border.
However, reading the other QA makes me extremely concerned because the OP was informed of their presence in No-Fly list only at the gate
Cost thousands of dollars hundreds of hours and and months in moral and mental pain.
Considering that sometimes people are refused boarding based on name mismatch and while redress inquiries do exist, I am still concerned about the possibility to lose thousands of euros, which are not a joke according to my wealth status.
Suppose that for some reason unknown to me I am denied flying over/to the USA.
Since according to European travel laws the carrier is obligated to protect passenger from denied boarding, if I happen to book a flight that journeys above the territory of the US (something a consumer cannot easily find out and it's not his duty to find) and I happen to be for whatever reason on a US No-Fly List, and I am revealed such information only at the gate,
Is the airline obligated to reroute or compensate me for denied boarding according to EU rules (EU261)?
- I have not yet intention to visit the US, maybe in the future
- I have no record or clue indicating I could be denied flying
- The total cost of the trip is absolutely worth being over-concerned
I tried to do some research on my own
This article provides a lot of guidance. In particular, I focus on:
You won’t be entitled to compensation in the following cases as well:
- You created or represented a health, safety or security concern
Being on a No-Fly list is surely a safety concern, but that concern is enforced by a third party national authority that does not have anything to do with my trip or the airline. The US has the right to put a ban to any people objectively deemed as a security threat, but also to people that may be unwanted because of political reasons (e.g. non-violent activists).
