A closer look
Airplane boarding from back to front is mathematically one of the absolute slowest and most inefficient ways to load a plane, yet almost every airline continues to use some variation of it because it protects the fragile egos of first-class passengers who pay to board early. Astrophysicists and mathematicians have repeatedly proven that boarding window seats first or boarding randomly is drastically faster, but airlines refuse to implement it because chaos allows them to sell priority boarding upgrades. You are standing in the jet bridge for twenty minutes watching someone struggle with an oversized suitcase entirely because the airline monetized your suffering and optimized for profit instead of speed
