Air New Zealand has suggested Qantas paint its planes black if the All Blacks win the Rugby World Cup against Australia this weekend.
The two airlines have taken to Twitter to suggest a friendly wager over the final.
Using the hashtag #AirlineWager, Air New Zealand today tweeted a picture of a Qantas plane in New Zealand colours with an All Blacks logo and other slogans.
Qantas responded with a picture of an Air New Zealand plane painted gold with Wallabies branding.
