I think that is fine as you are not making seats less accessible, I’m talking about when there are two people say next to each other and one swaps to the other side (in your scenario you wouldn’t swap if already by a window, and aisle to window is a neutral move), even though there are people hovering who want to sit.
I realise this may contradict my long held controversial ‘people who sit in the aisle when the window seat is free are fine and not people who’ position, but train etiquette is complex.
What makes this different, is that the awkwardness of asking to get by and sitting next to people is already a sunk cost, if they just stay put after people disembark it will be easy for the new people to take a seat without having to suffer that awkwardness, but instead the already have a seat privilege people take a gamble and spread out in the hopes they will have more comfort (or as the cynic in me suspects, a deliberate attempt to dissuade would be co-sitters), but inevitably the long suffering standing uppers are going to sit down, cancelling out the momentary gain of the sitter downers, but it’s more difficult that it needs to be. Think it’s fine to reconfigure after people disembark but there should be a reasonable window of time to let the stander uppers stake a claim
- That is definitely a people who, well spotted
- What are you talking about
