Will I have a problem?
 

Three days ago I found what seemed to me to be a bargain F fare on ITA Matrix of £2000 from OSL to BKK in mid-September, one way. It was available on Expedia so I bought it.

However, the Swiss site will not let me reserve a seat or see the meal pre-order for the ZHR - BKK leg although it did allow me to select a seat on the OSL - ZHR leg. Both Expedia and LX indicate the OSL flight is in J and the BKK one in F. I am just a little worried that this is a mistake fare which they will not honour. The J fare equivalent is now £2900 so although the F fare is not cheap it looks a relative bargain. Would one expect to be able to fully access the LX site with an OTA booking? Should I worry?

The J fare on the day I bought the F was about £1800 I think but I did not make a record of it so relying on my less than sharp memory!

I do have a six alphanumeric confirmation number from Expedia, that allows me to access parts of the LX site that I can use, as well as a ticket number but it begins 724.... which is suspiciously like the Expedia itinerary number which starts 726.... so I am not sure whether this is a real LX ticketed trip yet. (I don't normally fret about bookings but I am now booking no refund hotels in Bangkok and Chiang Mai as well as domestic Thai flights.)

One way not that cheap & have you tried reserving a seat on LH website ? Also look how many seats are for sale in F on the day.
It is not a mistake fare at that price ;)
724 are LX ticket numbers

Thanks a lot for this information, particularly the confirmation of the start of the ticket number.

I still can’t reserve my seat even on the LH website. Get the same message as I do on the LX site :

Unfortunately we cannot offer you a seat reservation for this flight segment. You may select your seat during Check-in

But not now worried; just anticipating the experience. Not too much though as a F on LH last year, eagerly anticipated, did not live up to expectations (notwithstanding the duck)!

Thanks again for the quick reply.

If the (724) ticket is issued and the reservation is visible on LX and LH.com you are good to go. You can call LX and ask for a seat assignment. The cheap F fares ex BKK are a feature, not a bug.

Call the LX F hotline during CH hours, they will reserve you a seat +41 848 365 365

This sometimes happens, not sure why. The hotline can assign seats.
