Re: Air New Zealand
This is the standard airline response and they won't budge! Interesting that in their conditions of carriage is the clause that they won't guarantee you a seat on the flight or the ETD/ETA. So what are you paying for? Claim on your travel insurance if you have any, you will have to pay the excess. Having said that, it is poor customer service and the airline needs to buck up! Chalk it up to experience, consider another airline in future! I had a similar experience last year with Jetstar and LAN Airlines, as well as ANZ in 1987!
This raises a whole bunch of legal theory around airline tickets, and a which point a contract is actually formed.
I think the most recent Australian decision on this was to do with GST, and the court ruled something along the lines that a ticket is an 'undertaking' to provide a 'future service' (or words to that effect).
Under ordinary contract law, there is quite a bit of theory to say that your 'contract' doesn't actually form until either (a) check-in or (b) once you actually take a seat on the plane. Until then, what you have would ordinarily be considered too vague to form a contract (exactly along the lines of 'we don't guarantee flight times, that you will even have a seat on the plane, we don't guarantee stopping places or that we won't have schedule and equipment' etc etc).
Probably the preferred view from the above camps is that a 'firm' contract is formed at the point of check-in. At that stage, the airline becomes responsible for you for matters within its control (including, for example, to provide hotels and meals if there are lengthy delays).
But of course these things rarely come to court as airlines don't want passengers setting precedent. The EU and USA have side-stepped most of the legalities of contract by introducing consumer protection laws.
Can flight times be made part of the contract at the time of purchase? potentially yes, but it could likely only be achieved by direct communication between the airline and the passenger. With appropriate acceptance by the airline that they were forming a binding contract. Likely to happen? Certainly not
intentionally by the airline in the case of ordinary passengers. And of course you'd be up for all the call centre fees for the airline to make the booking for you.
