I've just booked a 280k J aware for myself and MrsDaver6. I'll post more details of what we booked later but wanted to let you know how we managed to achieve it with minimal effort.
Firstly, I'm a bit time poor at the moment. The booking was for October/November this year. I had some flexibility with fixed dates. Ie, was doing a Norwegian cruise where I was flexible on which one, but once a start date was picked, the departure date from Norway became fixed.
I used
Award Flight Assist - Frequent Flyer Solutions which cost me $320. I cannot recommend this service enough. Extremely professional, great communication and helped me achieve pretty much what I wanted. If you don't know what you're doing or just want to save yourself the hassle/time, I would highly recommend thought route.
