1) a must admit that if the flt is booked full then we make a effort to fill the exit seats first with able bodied pax.
2)If pax who have pre-booked their seats then we will ring the gate with seat changes for people who have been split.
With ref to the first point i have had many phone calls from the ckin supervisor to say that they have done their best to seat able bodied pax in the exit and to pass the message onto the crew. unfortunately on some of our flts this is very difficult. (jer)
