No question will be considered stupid if you get a reward for it, and this becomes truer during a flight because many things which look awkward to ask for can be given for free, you just have to ask for it!
Usually you get a cup of soda which isn’t full and is filled with ice, so ask for can which the attended is obliged to fulfill or otherwise she will at least refill your cup.
[junkie-alert style=”green”] In many flights as an alternate to tea or coffee they provide hot chocolate, some flights even provide this service to their economy class passengers. Such as Etihad Airways, Virgin Atlantics and Southwest Airlines. [/junkie-alert]
Extra Snacks will also be provided to you on demand, because usually flights have remaining snacks after all customers are served, so if you don’t then it’s most likely that you will get more.
So stop being shy and ask for things which you need.
