When Do Airlines Release Flights for Booking? UK Dates and Booking Windows

One of the most common questions we get asked is a simple one: how far ahead can I actually book? The honest answer is that it depends entirely on the airline. Some open a whole season in a single announcement, others drip flights out airport by airport, and the traditional carriers work to a rolling daily horizon. This guide pulls the main UK airlines together in one place so you know when to be ready.

Two things are worth understanding before the detail. First, the low cost and leisure airlines release flights in seasonal batches, usually somewhere between ten and thirteen months ahead, and the cheapest seats are very often gone within days of a batch going live. Second, the lowest fare on a route is frequently the introductory fare on release day itself, because prices tend to climb as seats sell rather than fall. If a date matters to you, booking early usually wins.

The Quick Version

easyJet releases in three or four seasonal batches roughly ten to thirteen months ahead, typically during the working day rather than at midnight. Jet2 tends to launch each summer season in one very early announcement, often more than eighteen months out. Ryanair releases six to nine months ahead and does it progressively, airport by airport, so there is no single date. TUI launches its holiday seasons in big batches, with summer programmes going on sale the previous autumn. British Airways works to a rolling 355 day horizon, so a new day of flights becomes bookable every single day. Wizz Air releases in rolling seasonal batches around ten to thirteen months ahead with no fixed date.

Each airline has its own page below with the detail, the typical timing, and how to get the best out of a release.

How to Be Ready for a Release

The routine is the same whichever airline you are watching. Have an account set up and logged in before the release, with your passenger details saved so you are not typing them while the cheap seats disappear. Sign up to the airline's own email alerts, because that is usually the first place a new season is announced. Know your exact dates and airports in advance so you can search the moment flights appear. If your dates are flexible, checking the day either side of a weekend or school holiday can save a surprising amount.

It also pays to keep an eye on the airline's official schedule or flight release page, which is where new seasons show up first. If a route you want has not appeared yet, it usually means that batch has not been released, rather than the route being dropped.

Should You Book Early or Wait?

For the budget airlines, early almost always wins on popular dates. Prices are driven by how many seats have sold, not by how close you are to departure, so peak dates such as school holidays and Christmas tend to be cheapest on release day and only get dearer. The one risk of booking a long way out is that airlines occasionally change flight times after you have booked, though you are entitled to a refund or a rebooking if a change is significant. Our flight compensation guide explains where you stand if that happens.

Once you have your flights, our airport guides cover everything else. Every UK airport has live departure and arrival boards, parking, fast track and terminal information, and you can browse airlines directly on our airline directory.

We keep this guide and each airline page updated as new seasons are announced.
