This week's intelligence on flight bookings reveals a tactical shift, with significant reductions in flight-specific discounts, pushing more value towards bundled holidays. While CheapOair stubbornly clings to its 45% off flights, the real movement is elsewhere. Expedia, which last week matched the king with a flat 25% sitewide, has now pivoted to "25%+ Off Dream Stays" – a clear tactical retreat from standalone flight savings. This isn't about getting there cheaply anymore; it's about the destination.

The biggest let-down comes from Lastminute.com, which has completely abandoned its staggering £200 off all-inclusive holidays, instead offering a paltry 7% off Mexico, Canada & USA. This is a massive downgrade, effectively gutting a previous high-value asset for those who could weaponise a full booking. Similarly, Priceline maintains its "Up to $350 Off Packages", making it a more consistent, albeit less dynamic, option for comprehensive travel plans, especially now that Expedia has changed tack.

For direct flight hunters, the landscape has thinned. Kiwi.com, once a workhorse for multi-leg missions with £20 off flights over £100, has shifted to a "£20 Voucher for First Booking". This targets new recruits rather than repeat operatives, but it's still a tangible saving for those entering the market. Omio retains its solid "£10 Welcome Bonus" with no booking threshold, a clean entry point for new budget-fitter members. Conversely, Trip.com has veered wildly off-course, offering "BOGOF Universal Studios Japan" – a promotional stunt with zero relevance to cutting flight costs.

AirAsia MOVE remains adrift with "30% Off Duty-Free", a baffling move that continues to ignore its core flight offering. Booking.com's "15% Off Select Stays" is still a side-show, and Mytrip UK's "2% Off Everything" continues to be a token gesture. The strategic takeaway: standalone flight discounts are tightening. Value has migrated towards initial bookings or bundled holidays, forcing operatives to reconsider their approach to summer travel savings.

Booking a flight rarely comes down to a single price tag. The same route can swing by a wide margin depending on the day you fly, the airport you choose and whether you book on a website or in an app, which is why comparing before you commit matters more here than in almost any other category. BudgetFitter brings the leading flight search and booking platforms together so you can weigh comparison engines against full-service travel agents, then move to the lowest verified fare and any live discount codes without hopping between a dozen tabs.

How to find and book cheaper flights

The smartest approach is two-step: search broadly to understand the going rate, then book where the total cost, flexibility and extras suit your trip. Platforms like Expedia, Booking.com and Trip.com let you do both in one journey, while comparison-led services and agents fill the gaps when you want a specific route at the keenest price.

Comparison engines versus online travel agents

Comparison engines scan dozens of airlines and resellers to surface the cheapest fares, then pass you onward to complete the purchase. Online travel agents handle the whole transaction themselves, which can be more convenient and often unlocks package savings when you add a hotel or car. For multi-leg and budget-airline itineraries, services such as Lastminute.com and CheapOair are worth checking alongside the larger agents, as their pricing on the same route can differ noticeably.

Welcome offers and app-only fares

First-time and member offers are common across the category. Many platforms run welcome offers for new accounts and reserve their lowest prices for app bookings, so it pays to register and download the app before you search. Omio and other booking apps frequently tie member discounts to signed-in sessions, and BudgetFitter lists the active codes so you can see at a glance which ones apply to flights rather than only hotels or other travel products.

Flexible dates and multi-city searches

Fare differences between adjacent dates are often larger than any discount code. Whole-month and flexible-date views, available on most major booking sites, reveal the cheapest days to fly, while multi-city search opens up open-jaw routings that can undercut two separate return tickets. Being flexible on departure airport, particularly where several serve the same region, frequently delivers the biggest single saving.

Booking with confidence

Before you pay, read the fare conditions: baggage allowance, seat selection, change fees and the cancellation window. Cheaper headline fares sometimes recoup the difference in add-ons, so compare the final total rather than the lead-in price. As a verified aggregator, BudgetFitter only lists brands and offers we have checked, giving you a cleaner starting point than scattered code sites.

  • Search flexible or whole-month dates first to spot the cheapest days to fly.
  • Compare the full total, including baggage and seat fees, not just the lead fare.
  • Sign in or use the app where platforms reserve member and app-only prices.
  • Check whether a discount code applies to flights specifically before relying on it.
  • Confirm the cancellation and change policy, and pay by a method with buyer protection.

Frequently Asked Questions

Everything you need to know about flight search & booking deals on BudgetFitter.

What is the difference between a flight comparison engine and an online travel agent?

A comparison engine searches many airlines and agents to show you fares, then sends you elsewhere to pay. An online travel agent such as Expedia or Trip.com lets you compare and complete the booking in one place, often bundling hotels and car hire.

Do flight booking discount codes work on every fare?

Not always. Many codes apply to selected routes, cabins or app bookings, and some exclude taxes and carrier fees. Always check the terms before assuming a code covers your chosen flight.

Are app-only flight fares genuinely cheaper?

Several booking platforms reserve their lowest fares and member discounts for app users. If you book regularly it can be worth downloading the app, though you should still compare the in-app price against the website.

Is it safer to book directly with the airline or through a travel agent?

Booking directly simplifies changes and refunds, while agents like Lastminute.com or CheapOair can be cheaper and bundle extras. Whichever you choose, check the cancellation policy and pay by a method that offers buyer protection.

How can I find the cheapest dates to fly?

Use flexible-date or whole-month search tools, which most major booking sites offer, and stay open on departure airports. Midweek departures and early-morning slots are often the lowest-priced options.
