Last December, I booked BEY-CAI-ZRH return (on MS in J and LX in F) for July this year. I found out a couple of weeks ago that LX cancelled some of its CAI flights and so my return flight was one of them. Neither LX or BD notified me of this.

I am tossing between cancelling the whole itinerary altogether and booking somewhere else, or changing the return flight to TK (but currently no availability is shown).

Any advice on this? Thanks
By the way the dates are: 21 July for outbound, 26 July for inbound.
