Ryanair is cutting the price of its Porto flights on April 15, returning April 16, to £139 return.
The airline was offering return flights for £199, but the announcement that bmibaby was offering a day trip from Manchester to Porto for £149.88 forced their hand.
Ryanair's outbound flights leave Liverpool Airport on the day of the game at 07:00, arriving in Porto at 09:20.
The following day, you can either return at 09:45 or 13:45, arriving into Liverpool at 12:05 and 16:05 respectively.
Book with a Visa Electron card to avoid a £9.50 card charge, which would take the total fee up £9.50.
Also remember Ryanair's new compulsory check-in online system, which carries a £5 each way fee. So that would add another tenner on to the fee.
There are also other optional things to buy, like luggage space, priority boarding and insurance.
