UEFA is hoping to improve the travel efficiency throughout the Euro 2020 tournament by imposing minimum standards on airport facilities for host venues.
• FIFA probe World Cup bidding
With 13 cities set to share matches throughout the championship, the European governing body is moving swiftly to ensure fans are able to move between venues without difficulty.
All cities vying for hosting rights must have two airports in close proximity of the main stadium or offer at least two separate terminals to avoid clashes between rival fans.
The sanctions pose a difficulty for the Welsh FA, with Cardiff airport's single terminal essentially ruling them out of the bidding process, although further options will be explored
UEFA has also announced stringent criteria for stadium capacity, with the semi-finals and final to be played at a ground that can hold a minimum of 70,000 fans.
The quarter-finals must be held at a stadium with a minimum of 60,000 fans while 10 stadiums must have at least 50,000 seats and two host cities are able to hold just 30,000 people.
London, Madrid, Berlin and Rome are among the candidates to host the Euro 2020 final, although Istanbul is the favourite to feature the penultimate match.
The plans will be further developed at UEFA's executive committee meeting on March 28.
