When exiting an airplane, it is more efficient to remain in your row until the row ahead of you has accessed their belongings. This includes people that have no overhead luggage. Sometimes someone’s overhead luggage is behind their seat and it causes noticeable congestion/delays if there are people standing in the aisle obstructing their path. An exception could be made for patrons that need extra time for mobility issues, but this is usually arranged in advance with the flight attendants. Having said that, it’s best to make every effort to exit with expediency because there could be others that have very little time to reach their connecting flight.

It’s safe to generally assume that most others are equally (or more) tired of being on the plane and want to leave ASAP.
