If you've ever had coffee or tea on a plane, you probably already know that the water usually tastes terrible anyway. So, germs or no germs, stick to cold drinks. Like gin and tonic.
That's my philosophy. The Quinine will also help suppress any malaria one might catch due to humid conditions in the rear cabin toilets. Slice of lemon for a Vitamin-C immune system boost. The mild sedative of alcohol to drown out the screaming void of my mind left idle without access to the internet.

Consider doing something with your mind...
There's nothing as pleasurable as reading a book on a plane, as there's not much else to distract you. That's changing, though.
I find it unlikely the tonic you get on an airplane will have quinine.
Stick to drinks that don't stain. You never know when turbulence or a clumsy seatmate will spill a drink on your lap.
