The seats are assigned. People have been standing in line for 15 minutes now. Why on earth would anyone want to stand there, when they could just sit and wait until the line clears?
I understand wanting to get off a plane ASAP, but boarding? You just end up sitting on the plane, waiting for everyone else to get on.
If you have a bag to put in the overhead compartment then you want to get on sooner since the space is limited. I personally only ever take a bag that can go under the seat. I wait until everyone has boarded regardless of my group.
This is the correct answer. If I’m on an overseas holiday I’m usually carrying an extra bag of medication.
If I wait I run the risk of no storage space near me and it getting stored away from me
