I can understand the attachment to a seat. Emotional attachment, even though the logic that the seats would pretty much have the same view and other seat features. Personal buy in etc. Important.
Im not suggesting a seat would be switched for an inferior of materially different seat, e.g. end of row or even second from end wouldn't be valid for a switch.
Ive only thought this as i just bought 3 seats for me and 2 kids...and would have loved SWC, but had to go for second pref in the NEC. Dont get me wrong, as Im chuffed to bits with this, as 1st opportunity to have season ticket.
On the other hand. ...nice to have a few singles available in SWC for gen sale for those who want to drop in when they can.
Roll on next season anyway
