The term "extra legroom" refers to additional space provided for passengers in an aircraft, train or bus. This means that a passenger is given more room to stretch out their legs and move around comfortably within their seat. The extra legroom can be found in specific seats on the plane or train, usually at an additional cost, which provides more space between the back of the seat in front and the back of the passenger's own seat. This added space is particularly beneficial for long flights or journeys where passengers may experience discomfort from sitting for extended periods of time.
