When you're flying all night, one essential thing to carry is a bottle water.
This is very necessary as you find yourself thirsty most nights.
Bring an empty water bottle through security and fill it up at the gate. .
This assures you will have water on the flight when you want it. Jet-lag is caused in part by dehydration.
Have the flight attendant refill for u during the flight.
That way, you won't have yo wait for the periodic drink service when you are thirsty.
Its not a good wait I tell u, I have been there.
CAN YOU RELATE?
