United Airlines offers several ways to save on your travel plans, with the 10% Off More Flights deal standing out as the main promotion for booking your next flight. Whether you're flying solo or bundling in ground transportation, these offers cater to different travel spending levels, so choosing the right one depends on what you're actually buying.
Booking a single flight: The 10% Off More Flights deal delivers solid savings on any flight purchase. If you're a first-time visitor to United Airlines, signing up to the newsletter first may unlock special offers and promotions that could compete with or enhance this baseline discount, so check whether any newsletter-exclusive welcome offers apply to your booking before you fly.
Booking multiple flights or flying frequently: The 10% Off More Flights deal is your best pick here. The percentage discount compounds as your ticket prices increase, making this offer more rewarding than the flat 5% alternative when you're spending larger amounts on several bookings or higher-priced routes.
Adding car rental to your trip: If you're renting a car alongside your flight, the Up to 35% Off Car Rentals deal is worth serious consideration. You can combine this with whichever flight offer saves you most—the 10% or the 5%—to maximize your total trip savings across both bookings.
Comparing your options at checkout: United Airlines lets you choose one offer per booking, so you'll need to calculate which saves you the most money in your specific situation. When you add flights and a rental car to your basket, run the numbers: apply the flight discount first, then layer on the car rental savings to see your full benefit. For flights alone, the 10% discount outperforms the 5% option, but if a newsletter signup reveals an even better first-time rate, that path could beat both standard deals. Take whichever combination produces the largest dollar saving on your completed basket.
