Dear all,

I was looking at my bookings and selecting seats for future flights and I have noticed that throughout all classes (F, C, E, Y) random seats are blocked.
When I mean random, 2 middle seats in C in row 2 as an example, 1 window and 1 middle seat in E, random seats in Y. No bassinet rows or similar.
For F I guess 1 is blocked for infants.
Flights are 8 days to 40 days in the future.
Is there a specific reason and I can not select them even with SEN status, do blocked seats say something about loads, are they blocked for upgrades, etc ?

This is not a life threatening issue for me, but I would like to understand out of curiosity why this is happening ?

Thanks for your inputs!
