"Prescription" water bottle
I'm going to by flying Alitalia to Asia next month. I've always carried a bottle or two of water in my carry-on, due to a history of cancer (surgical removal of salivary gland and head/neck radiation). The FAs never bring enough water for my condition. Often they don't respond to pages, and if the plane sits on the runway a long time or the flight is turbulent, I can't get to the galley or the bathroom to get more water. I have called Alitalia and my travel agent to ask if I can bring aboard an empty bottle. I don't get any straight answers from them, but the general consensus is no. I thought I might try the empty bottle anyway, since the worst that can happen is it will get thrown away.
I would rather bring my own water than deal with dirty airplane water and unhelpful flight staff. I am a pharmacist and can easily generate a prescription label for just about anything. I am thinking of labeling an amber prescription bottle for water - but Rx bottles are awfully small. Has anybody had experience with a regular 500 ml or 750 ml water bottle with Rx label on it?
