2. Don't Ask to Cut
This is a big no-no, especially when it comes to the
security line, where dozens of other people are in just
as big of a hurry. Bear in mind that, when you ask one
person to let you jump ahead of him, you’re assuming
all of the people in line behind him will also be okay
with it. If it’s really an emergency, speak with a flight
attendant.
3. Share Overhead Storage
Space
The overhead bins are intended for multiple
passengers to share. If you take up too much room,
others may not be able to fit their bags in the
compartment. This is especially annoying if your
particular airline charges for each carry-on. If you need
extra room, speak to an attendant.
4. Know when to turn off
devices
Your electronics must be turned off during takeoff and
landings. It’s airline policy and, as such, flight
attendants are just doing their jobs by enforcing it.
Arguing with them accomplishes nothing and may
delay the flight. Additionally, if they view you as a
problem, you may get put off the plane.
