Accruing miles on ticketed carrier's FFP when re-routed to another carrier

[milehighj]

Question for you guys...

If the carrier on which you ticketed your journey re-routes you to a different carrier due to technical delay with their own aircraft, is there a generally accepted practice or obligation to accrue miles to their FFP, even though the journey was on the other carrier (and miles were accrued to other other carrier's FFP)?

I have this current situation where the ticketed carrier is refusing to accrue the miles and status credit...

MTIA.

Generally, people get miles on the FFP of their originally ticketed carrier given that it's not your fault you were re-routed (what if you required the miles for requalification etc). It may also be a bonus that you get miles on the FFP of the carrier you actually took. This is even the case if (say) travelling on LX and re-routed to BA. I would insist on your miles.

Agreed. In rare circumstances, I've seen both happen. If you need the miles, you have to make your case...and it could prove to be a difficult one depending on the carrier.

Thanks for your input chaps

The carrier onto which I was re-rerouted credited me with miles and status within 48 hours (in fact, jhm, I probably mentioned that to you over dinner already ). Just that the ticketed carrier is being difficult about their miles and status. In any case, my TA is helping with the case.

Ticketed carrier refuses to budge, despite pressure from my corp TA. Gosh, you'd think they were the arrogant home carrier we love to talk about so much, rather than an arrogant wannabe with too many A380s on order...
