Shops and restaurants will shut so workers can cheer Chris Coleman's heroes in their Euro 2016 semi against Portugal.

The winners will play Germany or France in Sunday's final.

Bookies estimate £30million will be staked on tonight's clash.

Wales boss Coleman admitted his team were "underdogs" but said: "It's about Wales, the players, about them walking on to the pitch knowing they're safe in each other's hands. They trust each other."

But last night up to 25,000 Wales fans with tickets for the semi-final were facing a desperate battle to get to Lyon in time after more than 200 flights were cancelled due to the 13th strike by French air traffic controllers in the past 14 weeks.

Four flights into Lyon airport were grounded.

Matt Jones, from London, could not find an alternative after his was scrapped and so forked out an extra £210 on train tickets.

John Mead, from Barry, Glamorgan, will have to watch the match at home after his flight from Luton to Montpellier was axed.

He said: "There is now no way of getting another as hundreds of easyJet and Ryanair flights have been cancelled. Welsh fans will now be unable to get to the match."

Fans switched to cars, trains and ferries to make the 800-mile journey from Wales.

Supporters were even struggling to get tickets to watch the game in fan zones in Wales.

All 20,000 to see the tussle on a 100ft screen in the Principality Stadium in Cardiff were snapped up in less than an hour.

Martyn Phillips, chief executive of stadium owner the Welsh Rugby Union, said: "The people of Wales have united together in celebration of this historic success."

Meanwhile, Cardiff bus company New Adventure Travel offered free rides to every passenger wearing a Wales football shirt while council chiefs in Swansea were also forced to move its fan zone to Singleton Park to accommodate thousands.

Chepstow racecourse is offering customers the chance to watch the tie on a big screen with a curry and a pint for £10 and tickets for a fan zone outside Caldicot Castle in Monmouthshire sold out in eight minutes.

Meanwhile pundit Robbie Savage vowed to cut short a holiday if Wales got to the final and tweeted: "Wife and kids understand."

And one England fan was also praying for Welsh success as he stands to pocket £80,000 if Wales win the tournament after betting £1,000 at 80-1 with Ladbrokes.
