Best Free Websites to Find Cheap Business Class Flights [2025 Guide]

Flying business class is often associated with high prices, but with the right tools, you don’t have to pay the full fare. A growing number of deal websites specialize in finding discounted premium tickets, including mistake fares, sales, and hidden offers from airlines that you’d never find on your own.

The problem? Not all deal sites are created equal. Some focus mainly on economy class, some mix in lifestyle content, and only a few are truly dedicated to helping you fly business class for less.

In this guide, we’ll compare the best websites to find cheap business class flights in 2025, and show you which one should be your first stop.

1. Premium-Flights.com (Best Overall for Business Class Deals)

If your goal is cheap business and first class flights only, then Premium-Flights.com

is the strongest choice. Unlike most deal websites, Premium Flights is entirely dedicated to premium cabins, no clutter, no economy deals to sift through, and no distractions.

FAQ: Cheap Business Class Flights in 2025

What is the cheapest way to fly business class?

By monitoring dedicated deal websites like Premium-Flights.com, using points and miles strategically, and staying flexible with dates and departure airports.

Are mistake fares still happening in 2025?

Yes, but they are rarer than before. Having alerts set up ensures you don’t miss one.

When is the best time to book business class flights?

Sales occur sporadically without set dates, so the optimal time to book is when a deal site identifies a discounted fare.

Is it cheaper to book through an OTA or airline directly?

Online travel agencies (OTA’s) may offer lower prices, and occasionally, some fares are only available through OTA’s, leaving no option to book directly with the airline. To reduce risks, stick to reputable OTA’s like Expedia or Booking.com. However, booking directly with airlines is generally safer for changes or upgrades.

Note: All deals are personally verified and bookable directly with airlines or reputable travel partners. Prices and availability can change quickly, we never sell flights ourselves.
