Thousands of Birmingham City fans are at Wembley for their team's first major final at the ground since 1956.
The Blues face Arsenal in the Carling Cup Final, which kicked off at 1600 GMT.
The club was allocated nearly 31,500 tickets, all of which have been snapped up with fans queuing from the early hours when they went on sale.
One Birmingham fan spent $1,800 Australian dollars (about £1,135) flying from Perth for the match.
Grant Megan arrived back at his Lichfield home, in Staffordshire, on Wednesday.
He said: "Three weeks ago I realised Birmingham had got into the final.
Beaten on penalties
"I got in touch with my brother and he came up trumps by getting complimentary tickets through work.
"$1,800 later - it is worth every penny, and the 24 hours to get here."
The club got through to the final by defeating West Ham in the semi-final, four goals to three on aggregate.
Blues lost to Manchester City in the 1956 FA Cup final.
In 2001 Birmingham lost the League Cup final - then known as the Worthington Cup - to Liverpool at Cardiff's Millennium Stadium.
Blues were beaten on penalties. The match took place in Cardiff as Wembley was being redeveloped.
