A last-minute guide to on-the-spot deals.
Follow Airfare Watchdog to get the next weekend's fare deals. For trips slightly further out, theflightdeal.com highlights fares cheaper than six cents a mile. For truly last-minute plans, try GTFO, an app that lists bargains for tonight and tomorrow.
At noon each day, the Hotel Tonight app updates room deals in hotels with vacancies in your selected area; we found savings of $5 to $60 per room compared with the hotels' own websites. Booking.com's app has a larger pool of hotels but smaller discounts.
If the hot spot you're after has no openings at your preferred time, an app called Rezhound alerts you immediately when a reservation opens up on opentable.com. Pay-to-play apps like Table8 or Resy — which split a fee with the restaurant — also help.
