Cheap European flights from the UK are still real — just less obvious than they were in 2015. The airlines that built the model (Ryanair, easyJet, Wizz) are still cheapest, but the prices change hourly, and the booking sites have learned to hide the cheapest options unless you ask the right way.

Skyscanner's two underused features

  1. "Everywhere" as destination. Type your home airport, leave the destination blank, search anytime in the next month. Skyscanner returns a sorted list of every country, cheapest first. Good for budgets like I have a long weekend and £100.
  2. Flexible-date grid. On any specific route, the calendar view shows the cheapest day in each month at a glance. Tuesday and Wednesday departures are almost always cheaper than Thursday–Sunday.

Airports outside London worth driving to

  • Stansted — Ryanair's UK hub. Routes nowhere else flies, prices nobody else matches.
  • Luton — Wizz Air's best UK base. Eastern Europe is unbeatable from here.
  • Manchester — second-busiest after Heathrow, with long-haul prices that often beat London if you live north of Birmingham.
  • Edinburgh and Glasgow — direct EU routes that don't exist from regional airports.
  • Bristol — easyJet's western hub. Spain and Portugal cheaper than from Gatwick by £30–50.

If a friend with a car can drop you at Stansted instead of the £15 train, the saving on the flight often clears the cost of the petrol several times over.

When fares actually drop

The folklore — book on a Tuesday — has a kernel of truth: airline revenue management systems update overnight, and Tuesday/Wednesday morning often surfaces the new cheaper allocations. This is more pronounced 6–10 weeks out from departure.

What's untrue: that incognito mode hides you from price-tracking. Booking sites don't raise prices based on your cookies in any documented way. The price changes are real; they just aren't personal.

The carry-on rules that catch out British travellers

Ryanair, Wizz, and easyJet all charge for anything bigger than a small backpack. The free cabin allowance is genuinely small: roughly 40 × 20 × 25 cm, fits under the seat in front, no overhead locker.

  • A rolling cabin case that fits the standard "priority" size (55 × 40 × 20 cm) requires Priority Boarding (~£8–14) on Ryanair.
  • A 35-litre backpack is the sweet spot — fits the free allowance, holds a long weekend's clothes.
  • Don't pay for hold luggage unless you genuinely need it. The £40 round-trip often exceeds the saving on the fare.

Mistake fares and how to find them

  • Jack's Flight Club — free tier emails 1–2 deals/week, premium does 5–10. Their genuinely cheap finds (Bali for £350 return, etc.) appear once or twice a year.
  • Secret Flying and Holiday Pirates post the same kinds of fares without the email. Watch them for a fortnight before any planned trip.

A pattern worth knowing

The cheapest week to fly to most of Europe is the first week after school summer holidays end (early-to-mid September). Weather is still warm; prices fall by 40–60%. The same logic works for late January and the second half of November — quieter, cheaper, and not noticeably worse.
