Jet2holidays is offering £100 off per booking with promo code SPRING100, and it’s valid on package holidays departing up to 15 November.
If you are booking as a couple, that is effectively £50 each off the total. For a family booking it can be a very tidy saving, and it is one of those rare codes that is simple, cash-off, and easy to understand.
The main catch is that Jet2 does not give an end date. The terms say it runs ‘until further notice’, which is a polite way of saying it can disappear at any point. If you were already close to booking, it is worth trying while it is still live.
- Saving: £100 off per booking (new bookings only)
- Travel window: departures between 18 March 2025 and 15 November 2026
- End date: none stated (‘until further notice’)
- Worth knowing: if you change passenger names or flight dates after booking, the discount no longer applies
