The delay tax: Why your airline voucher barely covers your expenses anymore 

When a flight is delayed or canceled, airlines cover only what they call duty of care: a meal voucher, sometimes a hotel, or a refund if the flight is canceled. Angela Justice received a $10 voucher after her Boston to Chicago flight was canceled. The real cost, the delay tax, is far larger. It includes nonrefundable hotels travelers cannot reach, lost wages, child care that keeps ticking, and the replacement flights passengers must book themselves when the airline’s rescheduling timeline proves useless. Airlines calculate compensation based on what it costs them to reschedule a flight, not what it costs the traveler to miss the reason they flew in the first place. The official story is that duty of care solves the problem and the Department of Transportation signs off. But the law was written in a different era, when travel was simpler and airlines were more generous, and regulators have not caught up now that delays are chronic and carriers watch every penny.

Aeromexico offered him a “free” flight change. Then it refused to give him one.

Jorrit Muller booked Aeromexico flight 335 from Puerto Vallarta to Orlando for a wedding. Three months before departure, Aeromexico shifted his flight one hour earlier, into the reception time. The airline notified him that if the new flight did not work, he could move to another at no additional cost. When he tried to use that offer through Aeromexico’s WhatsApp support, the available flights were operated by Delta as code-share. An agent told him to request a refund instead, then Aeromexico denied the refund. Under DOT rules, a significant change for international travel requires a schedule shift of six hours or more.
