" far too many seats are usually blocked off for Asisstance pax, and then later released during boarding ".
This is because we only get told how,any assistance pax there are, not how manyare travelling with them. Some also have assistance booked by insurance company, and have paid for three seats. We as crew don't get this information till the passenger arrives., hence so many seats blocked. There is nothing worse than not having enough seats blocked off , and then tryin g to move pax after.......,ost of which are speedy boarders in front rows, and will Not move as they have paid for the right to sit there. Then you delay boarding and stress people out!!!! It's best to over allocate and release, than under allocate and move!!!!!!
We also have no idea of their condition on boarding....whether they are a complete carry on ( which they need the row in front and behind empty to enable them to be lifted into position ) or have broken legs ( need to have leg on the three seats) or what. There is a reason why seats are blocked off, so please don't assume that it's always overly blocked off.
