Useful indeed, and thanks, Stunt!
Some additional info:
1)One airline not listed is EVA Air, a Taiwanese carrier. We're flying EVA between Toronto and Brisbane in January & March 2018. EVA's fares are much better than any of the other carriers, by a factor of at least 40%, sometimes more.
BUT, their bikes-on-planes allowance is much more restrictive than, say, Air Canada's:
> total linear dimension allowed is 80" / 203.2 cms. This means a box of 40 x 30 x 10. My current box is 85", well within AC's limit of 115". I think I can fit my Raven into the 80" limit, with some disassembly.
> weight limit: up to 23 kgs. Cost for that is Cdn $130. Over that limit, cost is about $400, but no larger box is allowed. (By comparison: On our last trip to Australia, Feb 2017, AC's fee for my bike was $75, but for some reason AC did not charge me. My bike was one of my 2 pcs of checked luggage.)
2) A note on Virgin Australia: In early April 2017, we travelled from Gold Coast (Queensland) to Sydney on a domestic flight by Virgin Australia, connecting to our Air Canada Sydney-Ottawa flight. I had checked Virgin's bikes-as-baggage policy before booking our flights, and Virgin's policy is essentially the same as AC's. (My bike box measured 85" and weighed a little over 23 kgs.)
> I had printed the Virgin policy before flying, and I had double-checked it by phone with a Virgin employee before flying in April, to let them know that I'd be putting a bike in the hold. Just as well, because the otherwise-helpful staff member at the check-in counter did not want to accept my bike, as it was more than 23 kg. I showed her Virgin's policy, but she wasn't impressed. I gave her the name of her colleague and the time of my recent conversation, and told her that I had booked Virgin six months earlier because the policy allowed my bike. Eventually she reluctantly agreed.
