In a staggering testament to modern inefficiency, the $52.3 billion drain on airlines is just the tip of the iceberg, as stranded passengers collectively wasted a billion extra hours, burned enough fuel to make an environmentalist weep, and triggered a multi-billion dollar cascade of missed meetings, missed connections, and hotel vouchers, proving that time, money, and sanity are the true casualties of a system perpetually stuck on the tarmac.
