An underage asking for alcohol in the plane?

I am going on a freaking 14 hour air-plane trip, and from my experiences, that will be hell of time to spend. So I am planning to get some alcohol and try to sleep off the whole trip. But then I am 17 and if I ask the stewwart(spellingX), do they check for your license? Or do they just look at you and judge it themselves? I look pretty mature in my opinion, but I bet my L license wouldn't work. Do they serve alcohol?

Ok, no sarcasm or anything. The only reason i want alcohol is so that I can fall asleep. And I am not talking about getting drunk and having a party here.
Just enough to make my eyes closed.

Yes some airlines serve alcohol, and depending on the cart lady or man they may just server it to you. But they have the right to ask you for an ID and refuse giving you alcohol considering its illegal for minors. Just try asking for some and if they ask for an ID say im sorry but its out of reach and if they still refuse say alright just get me a soda. (something to the tune of that)
