Codeshare, Route changes and Mileage
 

As part of my LONE4 I'll be flying SYD-HNL. AA has a codeshare on this flight which I intend to use. I was told that this route will possibly no longer be flown by Qantas when I plan to fly (next July) and that Jetstar will take over the route. If this carrier change goes through, and there is no codeshare with AA, will I still be entitled to the mileage and points that I orginally booked on?

Also, am I correct in thinking that using a codeshare earns you the same miles and points as if you were flying on the codeshare's own metal? (i.e flying an AA codeshare on Qantas metal earns the same as flying on AA Metal)

Thanks

Yes, that is correct, it's what your ticket says that counts, you fly on a AA flight number, you earn as if it were an AA flight.
If there is no codeshare with AA, you should still be able to fly the route, though only earning 50% miles in L instead of 100% with AA.

If you have a confirmed and ticketed booking before the change and was protected on other carrier as a result, you should be entitled to the mileage and points which you were confirmed for. If not, I don't think so.

I don't think JQ is a valid carrier for LONEx tickets. :(

I think the rules say something about Jetstar being a valid carrier in certain circumstances, but not many. Thanks for the info about the protection I would have if the carrier does change. I have open dates on most of my tickets, but plan to date a lot of it soon.

You seem to understand the significance of open dating, but for the benefit of anyone browsing this thread in the future:

- dated segment: protected to be routed on another carrier or routing if necessary, including credit for the mileage earned by the original booking (this may even be onto a non-OW carrier).

- open-dated segment: you are out of luck and must make own arrangements, including using more segments for a different routing. No protection for anything ... with open-dating you assume 100% of the risk.

Is that written somewhere, or just the way it usually works?

A bit of both. See this link.

Edited to add: note the reference to 'as ticketed'

It is written in the Conditions of Carriage of most airlines (probably all of them). The difference is that a dated segment becomes an involuntary reroute, while open segment is not.

I'd still like to hear from someone what possible benefit an open segment has in the current e-ticket environment, where changing dates is now so easy. I did use open segments on paper tickets, with good reason, but now I cannot see any value to it at all. Actually most airlines have also made changing dated paper tickets much easier than it used to be (BA will even take it unendorsed for non-BA vouchers, guess they are hungrier now for revenue).

I suspect this is true for most OW airlines, I have made unendorsed changes to paper tickets and neither LA nor QF batted an eyelid. Which was a shame, in truth, because LA have some quite attractive staff ;)
