Tui found itself in hot water with the Advertising Standards Authority (ASA) thanks to a Las Vegas holiday listing that went up in price by more than £700 when the user clicked through to checkout.

EasyJet, meanwhile, was censured after stating in an ad passengers could take large cabin bags onboard "from £5.99". The ASA ruled there wasn't sufficient evidence the price was available across a wide enough range of flights and dates for the claim to stand up.

Both firms have been told the relevant ads, listings or communications must not appear again in the form complained of.

Tui

The Tui complaint arose from a holiday listing on tui.co.uk for the Caesars Palace Hotel in Las Vegas, seen on 2 July 2025 by a journalist for a consumer-focused travel guide.

The holiday was listed for £1,248.13pp and at a "total price" of £2,496.26 with text below the price stating "price may update at checkout based on availability". Further text, in red, stated "Inc £187.74 total discount", referring to an online-only discount.

However, upon proceeding to the next stage of the checkout process, the price appeared as £1,608.44pp and at a "total price" of £3,216.88 – an increase of £722.62.

Accompanying text stated this was due to the holiday featuring flights from a third-party airline. The text added: "We receive the latest prices from the airline a few times each day but, the price might change when we come to request the actual seats."

Responding to the complaint, Tui said it could not retrieve specific pricing data for 2 July 2025 owing to the volume of dynamic combinations and associated costs.

However, when reviewing the data, Tui identified a fare filing issue with a particular airline concerning the booking in question, which it believes led to the discrepancy. That airline was removed from package sales until the issue was fixed.

Tui was able to provide the ASA a screenshot showing the same Las Vegas holiday on 20 October 2025 with a higher offline price and lower online price which it believed reflected the discount.

The operator added that since 2023, it had included the wording "price may update at checkout based on availability" to its hotel deals and summary pages to "make it clearer to customers that prices may be subject to change".

In its ruling, the ASA said marketers should take "reasonable steps" to ensure prices that are subject to change are described as "from" prices and should make clear the date of the last price update, which was not included in the listing.

In addition, it said that given the prices on Tui's website are frequently subject to change, the basis of the comparison leading to the £187.74 discount claim was not made clear.

The ASA has told Tui to ensure advertised prices are based on genuine prices available to consumers, and to take steps to reduce the likelihood of consumers being misled, such as by describing prices that are subject to change as “from” prices and stating when they were last updated.

EasyJet

EasyJet, meanwhile, was challenged by consumer watchdog Which? to substantiate a claim on a "Fees and Charges" page on its website, seen in September 2025, that customers could book "large cabin bags from £5.99".

The airline said the page in question was intended for information purposes rather than promotional or marketing purposes, but insisted large cabin bags could be purchased across its network for prices starting from £5.99, and that this price was accurate and available "on a range of routes".

However, it stressed that because prices for large cabin bags varied depending on factors including availability, demand and operational cost, it was not possible to display an exact price on the Fees and Charges page.

EasyJet added the page was intended to inform consumers £5.99 was the starting price point for a large cabin bag.

The ASA said it considered consumers would understand the "from £5.99" claim to mean large cabin bags would be available to book for £5.99 across "a significant proportion of flight routes and dates".

It said it expected to see evidence of this, but easyJet was not able to provide specific data to substantiate the price.

It ruled that while it acknowledged easyJet's assurance large cabin bags could be purchased for £5.99, it did not consider this alone to be sufficient to substantiate the claim.

The ASA added: "Because we had not seen sufficient evidence to demonstrate that large cabin bags were available to book for £5.99 across a range of flight routes and dates, we concluded the 'from' pricing claim had not been substantiated and was misleading."
