I don't see any reason to use the business saver fare anymore - I'll be going in economy unless I'm connecting onto a long haul flight.

I'm currently looking to book a business flight to the US in November, and most of the sub £3000 fares are coming in as P. It looks to me like they have just replaced the Z fare with the P fare, and moved the cost of Z up to a similar cost as J and C. I'm guessing that the marketing department thought that it would be better to create a new fare class than just devaluing Z to 100%.

As most of my long haul is in Z, it will probably be the end of me using LH group airlines. I'm even considering going back to Sky Team starting next year.
