As someone who has been "assisting" bmibaby, I can confirm
that the check-in staff are very hot on "tatty"passports.
The state of some have to be seen to be believed.
As MerchantVenturer has stated, if the photo flim covering has been disturbed, then they ain't going anywhere.
They then go off and try and glue the photo down, which only makes it worse !
If the staff weren't so hot on it 6 months ago, I can tell you that it's been drummed into them now, with the threat of letters on file etc etc.
I've turned away pax, myself and the abuse level is tremendous, which usually tells me that they know they are in the wrong.
Ho hum.
