Consider boarding an aircraft on one of the major airlines. Usually there is a line for "preferred customers”. You know, those for military, then those with difficulties boarding, those with small children, first class, business class, platinum class, gold class, silver class, and finally those of us with "no class” can get shuffled to middle seats with the overhead baggage already full. Simply take your time and rank the most efficient boarding methods, showing your work and references for why you believe it is more efficient. Also, suggest why most airlines use less efficient mechanisms to board passengers.
RANK These five and explain
"Class and mileage” (military, first, business, platinum, gold, silver, main cabin)
Check-in sequence (first to check-in during 24-hour period board first)
Window seats, then middle seats, then aisle seats
Row number, back to front
Boarding sequence assigned in advance, open-seating
