To get more attentive service from your flight attendants
"While most passengers tend to choose seats that are at the front of the aircraft, so that they can disembark first and have a better chance of securing their preferred meal option, flight attendants know that if you're sitting towards the back, you'll receive the most attentive service.
"The reason is simple: We like to avoid responding to call bells from the front of the plane because answering one means potentially flaunting whatever item the passenger has requested to everyone else along the way. This can cause a problem since planes often don't have enough extra vodka, pillows, earplugs, and toothbrushes, or the time on shorter flights to deviate from the service schedule.
"For passengers sitting near the back of the plane, however, it's much easier to slip in that second mini bottle of wine."
