Most carriers will auto rebook onto the most convenient routing, but they cannot determine the individual passenger's preference. Thus, the first thing to do is to look at alternative routings and have those ready for when you call. By providing specific flight numbers, you make this easier.

You may also find that the scheduling is such that J is the better alternative and you then have to make a decision.

For an involuntary reroute, you are due a refund of the fare difference between F and J for the downgraded segment. Make certain that you deal with this as a refund, not compensation as the two are entirely different.

Always great to see there are other FT members onboard this mistake fare tonight. I`m on the same flight and will miss my CX888 HKG-YVR-JFK flight. Rebooking options are pretty limited due to full flights in asia. They put me onto the CX830 next morning. Hotline told me no hotel acommodation will be provided, checkin agent told me he thinks there should be something. Hope they are organized in HKG because i want to get at least a few hours of sleep...

I know its goodwill but anyone knows if they provide some sort of compensation for the delay like a travel voucher?

I'm 99% sure that (1) they'll put you up at a hotel in HKG and (2) no compensation save for a few thousand miles if you are an MPC member; I hope you have travel insurance

IMO CX keeps being quite silly with that VN fare. First, they make the mistake, then it takes them a very long time before they notice and remove it, then they honor it, and now they compensate one segment downgrade for more than the price of the whole ticket.
It does not sound like a well-managed company.

Yes, it is silly but the public love it and CX wins reputation
It might be a win-win stiuation

I would have thought CX could have argued their way out of it by just forcing a reroute or downgrade with an upgrade cert (wink-wink) or fare difference at the time of booking which could have been less than US$100

I second that it is stupid. A refund should never exceed the price of the whole ticket. Else the next time they have a J or F mistake fare, people will buy it in droves hoping for the excessive "refunds" on one of their tickets.

You missed the "if" word. Would think CX has learnt enough lessons from its mistake fares.

I think there will be. SQ is tight with its fare publishing controls, and is strict in that it is known to downgrade holders of error fare/ fuel dump tickets on day of departure. And yet the mistake with the JFK-FRA routing tables.

I wish SQ luck operating flights from the European Union... If someone fights them then SQ might well receive a slap on the wrist and have to cough up some dosh. Unfortunately such regulations can only help those few flights.

That's it. I am done with Cathay. I just read the unbelievable story about the compensation in cash for a downgrade from F to J on the mistake-fare ticket. I have been loyal to Cathay for over 18 years now. I have spent a fortune on flights. Never mind the service downgrade, never mind the tighter cabin configurations. But if they literally throw money out of the window I am going to spend my hard-earned bucks on other carriers. I have been downgraded for a least two or three times due to a equipment change - mostly on F-award-tickets on regional flights. The most I got was the difference in miles spent - 10'000 or 15'000. Should I have asked for 100'000. Seems to be more appropriate under the new policy.

Sorry to hear that. Personally I have never encountered any downgrade but here is my friend's story.

He redeemed AM to a TPE-HKG-LAX return ticket, all four legs were F class.
One the last leg, HKG-TPE, he got downgraded to J and recieved 500 HKD cash.
For such a short flight, it was good offer.

I dont know why he got cash but you only got mileages refund since both were reward tickets. mystery...
BTW, he was only a MPC GR...

I have checked with CX on this matter and it is FAKE NEWS and someone is making this story up to hype up sensational news.
