Thanks for all the replies!
I think AirNZ is our best bet. It’s £130 for an extra 23kg bag, so we’d get 2 bikes and 1 120L duffel through I think! Whereas Emirates will charge us an extra 50USD per kilo over our 30kg baggage allowances.
We had a look at shipping it but we’ve no final destination and won’t do for a while so it would be a fussier option we think.
AirNZ don’t fly through America anymore which saves that hassle.
Luckily we’ll be fitting new tyres before we go after a busy summer traveling and riding.
Unfortunately we have to have travel insurance with our visa, I’ve found one for £500 odd with holidaysafe, who I’ve used before, and they’ll do an annual long stay trip. Just need to email them and check it will definitely cover us.
I’ve flown with a bike bag and a box before. I had to take the box apart and faff so much with that at Geneva where as the bag was so much simpler. After that, I prefer bags anyday.
Manchester is our local airport, and I know to add an extra hour or two to arrival time when flying with bikes or skis! Never had anything taken though 🤔
Thanks for all the advice! It’s been super helpful 🙌
