The crew of Irish airline Aer Lingus has swallowed its pride and donned All Blacks tops after losing a bet to Air New Zealand.

The two airlines made a public pact before yesterday's Ireland v New Zealand rematch in Dublin - betting that the losing nation's national carrier would wear the winning side's rugby jersey.

It came after a back-and-forth between the two airlines' Twitter accounts ahead of the big game, which saw Ireland lose 9-21 on home turf at Dublin's Aviva Stadium.

The airlines sparred over Twitter, throwing out some interesting proposals - from boarding passes and in-flight magazine covers, to airport revamps.

They finally settled on a cabin crew uniform change if their side lost.

Today Aer Lingus posted a short video of Air New Zealand crew handing over All Blacks tops for them to wear.

The four crew members in the video smile and hold them up - however forced the smiles appear.

But the airline said it all when it posted: "A deal is a deal."

Air New Zealand was a gracious winner though, telling the rival airline: "Great game @AerLingus and @IrishRugby. Thanks for being great sports. #AirlineChallenge"
