Air New Zealand is investigating reports some of its off-duty cabin crew became drunk and cuddled All Black players on a flight home from the United States.

The crew are under investigation after Thursday’s NZ1 flight from Los Angeles, which brought the All Blacks home from their northern hemisphere tour, the Sunday Star Times reports.

One of the off-duty crew allegedly became drunk and abused the operating cabin crew, while a second was also drunk and “cuddling” a player.

Leeanne Langridge, general manager cabin crew for Air New Zealand, confirmed in a statement on Sunday that seven off-duty cabin crew were travelling back to Auckland as passengers on the flight from Los Angeles, which landed on Thursday morning.

“There was a suggestion that some of the crew travelling back to New Zealand as passengers may have consumed too much alcohol and the matter is currently under investigation.

“Given this is an employment issue, Air New Zealand will not be commenting further,” she said.

The world champions ended their season with a come-from-behind win against Wales that crowned their successful year.

After crushing tier-two opponents the United States 74-6, the All Blacks struggled in the UK, using second-half composure rather than flair to pip England 24-21 and Scotland 24-16.
