indeed, like AY policy to request to see your visa for India despite you doing a airside transit and all tools (like timatic and real-life-experience) says "No visa needed"....

I have a similar situation when entering Japan, as there is a maximum 180 day in total per 12 months and they technically would need to calculate dates from multiple landing permits and exit stamps. But never any questions on that route.

I guess what I wanted to say was that if EU is "striking down" on airlines for not checking a complicated stay rule, they should at least offer a way to do it more easy. Like validating the passport against a database of registered stays. Computers are much better at checking dates than people are.
