Consumer finance expert Martin Lewis has issued an urgent alert for travellers hoping to secure cheap summer flights, warning that EasyJet is set to release thousands of seats on Tuesday morning and that prices will increase rapidly after the initial launch. The MoneySavingExpert founder advised customers to set their alarms and book as early as possible to avoid paying significantly more.

Lewis said in a statement that the airline's upcoming sale represents one of the best opportunities of the year to lock in low fares for summer 2027 travel. He stressed that waiting even a few hours after the release could mean missing out on the cheapest deals. «This is not a drill,» he said. «If you want cheap flights, you need to be ready to book on Tuesday morning. Prices will not stay low for long.»

EasyJet has confirmed that thousands of flights will go on sale from Tuesday, covering a wide range of destinations across Europe and beyond for the summer season. The sale includes routes from all major UK airports, including London Gatwick, Manchester, Birmingham, and Glasgow, as well as regional bases such as Bristol, Edinburgh, and Belfast. The airline expects strong demand as holidaymakers look to book getaways for the peak summer period.

The release is part of EasyJet's annual July sale, which typically offers some of the lowest fares of the year. The airline has been expanding its network, adding new routes and increasing frequencies on popular services. For summer 2027, EasyJet has already announced additional capacity on routes to Spain, Greece, Portugal, Italy, and Turkey, as well as new services to lesser-known destinations such as Pula in Croatia and Kalamata in Greece.

Lewis's warning comes amid broader trends in the travel industry, where early booking has become increasingly important for securing competitive prices. Airlines have adopted dynamic pricing models that adjust fares based on demand, meaning that the cheapest seats are often snapped up within hours of release. Martin Lewis has long advocated booking flights as soon as they become available, particularly for peak season travel, and his latest advice reinforces that strategy.

The consumer expert also highlighted that Tuesday morning is traditionally the best time to book, as airlines tend to release new inventory early in the week. He noted that many competitors schedule their sales for Monday or Tuesday, giving savvy travellers a narrow window to compare options before prices rise. «If you miss Tuesday morning, you may end up paying hundreds more,» he added.

EasyJet has not commented on the specific timing of the release beyond confirming Tuesday, but the airline has a history of launching sales at 6am or 7am UK time. Travellers are advised to check the EasyJet website or app early on Tuesday to secure the best deals. The airline has also introduced a price guarantee on some routes, but Lewis cautioned that the guarantee does not always apply to sale fares.

The sale comes at a time when the travel industry is experiencing strong demand, with many Britons prioritising holidays despite cost-of-living pressures. EasyJet reported higher passenger numbers in the first half of the year and expects summer 2027 to be similarly busy. The airline has also invested in new aircraft and technology to improve the customer experience, including expanded seat selection and baggage options.

For travellers, the key message is clear: book early on Tuesday morning to secure the best possible price. Lewis's advice is based on years of tracking airline pricing trends and consumer behaviour, and he has a track record of helping millions of people save money on travel. Those who follow his guidance are likely to benefit from significantly lower fares compared to those who book later in the summer.
