As you may have heard, Ireland are set to face Denmark in the play-off for next year's World Cup in Russia.

Ireland will travel to Copenhagen on November 11th, and then Denmark will play the second leg away here in Dublin on the 14th.

Needless to say, fans on both sides will be travelling through the airports in both cities, and the Twitter accounts of Copenhagen and Dublin Airports indulged in some top-class banter and good-natured ribbing yesterday.

Let's hope everyone's still feeling as friendly come the morning of November 15th...
