TUI launches weekend-only flash sale: up to £500 off holidays plus extra savings for summer 2026

TUI’s latest holiday sale has just been improved with a limited-time flash deal, giving you the chance to save even more on summer 2026 departures including July and August (aka peak school holiday territory, where bargains are usually thin on the ground).

TUI’s 'biggest ever sale' is already offering up to £500 off trips across a huge range of destinations and now you can get an extra £50 off per adult for departures in July and August, 2026. This extra weekend-only discount ends at midnight on 2 February - perfectly timed for some payday planning. 

AND both promotions are valid alongside TUI's free kids' places deal so you can score some impressive savings right now.

• Up to £500 off holidays for travel between May 2026 and October 2027

• Must be booked using a myTUI account

• Use code SALE at checkout to save

• Flash sale perk: get an extra £50 off per adult on July and August 2026 bookings

• Minimum spend £500

• Flash sale ends at midnight, 2 February 2026

• Excludes selected city destinations

Why we love it 

TUI sales are always popular with Mumsnetters because they cover loads of family-friendly destinations and this offer is particularly tempting because it includes summer 2026, when prices are usually at their highest.

If you’ve been waiting for a nudge to lock in a sunny escape, a long-haul adventure or a classic all-inclusive week somewhere easy, this is it.
