Certainly , any drinks containing caffiene, or that are carbonated (or both i.e.pepsi/coke) will make you urinate more frequently.
This is because they are diuretics which expel fluid from the body rapidly.
I would suggest no tea/coffee/fizzy drinks on yr day of flying, maybe a halfjuice/half water mix pre-flight, and then just sips of mineral water during your flight.
You can always recharge with extra water /drinks when you are 'back down' .
Drinking extra water/squash in the evening before, will mean theres a more than ample supply of hydration for you the following day without the need to go all the time.
