Budget airline Ryanair was today convicted of misleading British customers about the price of flights.
A jury at Chelmsford Crown Court, Britain found that the firm was guilty of six breaches of the Consumer Protection Act.
Trading Standards officers, who brought the prosecution, argued that Ryanair had failed to spell out the full cost of seats because the cost of insurance and tax was not included in the initially advertised price on the company's Internet website.
Ryanair had denied any offence and said the prices were not misleading because customers were told that the fare did not include tax charges.
Sentence has yet to be passed.
Meanwhile, Ryanair has received 200,000 advance bookings at its new Shannon base, which starts in May.
The allegations related to the cost of flights from London Stansted to various European destinations.
The airline will operate nine routes from its Shannon base and expects to carry over 1.5 million passengers over the year.
