My partner and I are trying to travel over Christmas to Europe using points, business class. What routes in and out of the country should I look at? I am struggling to find any availability for business period. I am happy to fly out of any city.
Welcome to AFF.
I think you'll have mostly missed the boat on availability for Christmas(which always would be very limited as is) - a peak time of year. QF's recent reward seat release would have potentially had some options, but they would have been taken.
You will probably need to try for the long way - eg: CI flights via TPE, or UL (Sri Lankan) via CMB., or looking from places in Asia for rewards on say Emirates to secondary european cities may also be an option. You may need to consider options like a paid fare on Jetstar or Scoot or something to position.
If you are Platinum or above status, you may have some joy with seat release requests for QF operated services, but this is also probably going to be difficult.
If you manage to find something grab it because they will be unicorns by now unfortunately.
I don't mean to discourage you but to be realistic, but you're after one of the holy grails of rewards, and the seats have been offered for several months already and savvy folks have grabbed anything available already most likely. I'm not saying it's impossible, just very very difficult, and will take quite some work potentially and you should be prepared to make compromises (perhaps looking for Premium Economy or even Economy on some routes and airlines).
best wishes, and again welcome to AFF.
