Well I will see what happens ex-IAH on Friday.
Left me bloddy glasses at home, so only on my contacts and some cheapy reading glasses from WalMart (hey, I've travelled less that business class across the pond for the first time, so may as well start slumming it at WalMart now

).
I did find some all-in-one, but it is 118 ml (4 oz). I am hoping I can take it on board so I can pop out me lenses during the flight to get some kip and then put them back in? Or has anyone had any experience with the night goo for the longer wear ones?
