Ryanair will lay on three flights - one going, two coming back - to ger reds to Porto.
United play there in the Champions League quarter final second leg on April 15.
And, with no direct flights from Manchester bar the chartered trips laid on by United, Champion Sports Travel, Miss Ellie Travel and Low Cost Sport, getting there is hard.
Today, Ryanair said they would charge a flat rate of £199 return for return flights.
The 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 to £208.50.
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.
