Standby tickets are inherently risky as they operate on a "seat roulette" basis, where boarding is only confirmed minutes before the aircraft doors close. Passengers on standby—often employees, their families, or those using "buddy passes"—are only cleared if there are empty seats after all ticketed passengers and high-priority "revenue" standby travelers (like those from missed connections) have boarded. This risk is amplified during peak travel seasons, holidays, or on popular routes where no-shows are rare. Travelers risk being stranded at a hub for days or having to purchase an expensive last-minute full-fare ticket if the standby list is too long. To mitigate this, savvy standby flyers aim for the first flight of the day, check "load" counts religiously on airline apps, and always have a "Plan B" (like a hotel budget or an alternate routing). While they offer massive savings—often 90% off—they are not recommended for time-sensitive trips or those with non-refundable hotel bookings.
