Maybe so, but if you have a cast iron gut like mine (and now it seems my son has inherited it) a dead pigeon in the water tank is neither here nor there...
As you could have deduced from those saying they ask the cabin staff to fill it up, it's for when I'm *ON* the plane, not walking to it. When I'm sleeping on a long flight, I often half wake up feeling thirsty (cabin air is very dry). Rather than get up and go to the galley, or attempt to get a cabin crew member to bring me a stupid little cup of water, I just take a sip from the bottle I have next to me and go back to sleep.
Tune in to tomorrow's episode: How Adrian takes his own bathroom tissue with him on flights to Singapore and how to save getting up for a mere number two.
I'm going to invent a camelfront. It looks like a fanny pack or a backpack, is filled with water and has a long tube to drink out of. No need to juggle around looking for a bottle of water. It's always in front of you, ready to sip.
I spoke with a friend who works at thiefrow.... the security manager has confirmed empty bottles ARE ALLOWED through security check without restriction.
As in my case they were not allowing bottles through, the passenger is advised to request contact is made with a supervisor to clarify the current policy.
Kiosk sells water behind the security for 1.50, it is the weird budget brand (forget the name, maybe "ok!", the bottles are maybe white and black) but it tastes fine.
You do know that Evian spelt backwards is Naive don't you? :-) Why buy bottled water when tap water will do. Just carry an empty water bottle around with you and fill it from a tap or water fountain when necessary.
What??? There is no prohibition on carrying empty bottles into the secure area of any airport. The prohibition is on liquids above 100ml. An empty 5L plastic bottle is acceptable. As is an empty stainless steel bottle.
I think it is only in the UK they do silly things like put water tanks in the roof, even there the cold tap in kitchens are connected directly to the mains.
I always keep the plastic bottle of water up until the minute they tell me I'm not allowed to take it through security. Then, I immediately drink it all, right in front of them. I am usually allowed to keep the empty bottle.
Even so, sometimes the newly empty bottle has been confiscated as has, on two occasions, a completely empty plastic bottle found in my hand-luggage.
