Three years ago I noticed a water stain on my 2005 UK Passport. Returning from Greece, it went unchallenged at any stage.
As the photo page was and is still perfectly legible and the integrity of the paper itself in no way changed I have continued using it.
There is no bubbling of the laminate, and the only thing noticible is a slght heightening of the blue colouration around the bottom left of the page, the photo itself is not affected. It is due to expire December 2015. Yesterdays Guardian Money section referred to instances of Easy Jet rejecting water stained/defaced passports. In the last three years since the stain took up residence on may passport (No idea what caused it, one minute it was fine next there it was, never damp that I noticed) it has been used 7 times no questions asked by easy jet or Thomas Cook, or even remarked on.six of the oinstances I have used it were with easy jet at Gatwick. Should I replace it now just in case? What would you do?
