Yeah, I am. I'm using United's website and clicking on each individual day instead of relying on the monthly grid which pretty much only shows 200K miles for business. What airports have you been looking at? I check PHL and EWR every day. Only a very few of the flight possibilities are fully business class--most have a leg in economy. I see United and I see lots and lots of Air Canada. I have never seen any biz savers for Air New Zealand.
I used to be able to see business savers that connect out of Houston, LAX, and SFO, but in the last month or so I only see ones through IAH. I'm not really happy about flying through IAH during hurricane season (we'd be going sometime in Sept or Oct next year). I hope those LAX and SFO connections w business savers reappear for me. Air Canada through Vancouver would be fine, I assume.
As an example of what I'm seeing---this was availability for 2 this morning from PHL for 2020
Mon 8/17 Air Canada
Sun 8/16 Air Canada but really long connections
Sun 8/2 Air Canada (same as above)
Wed 7/29 United through IAH with multiple choices; Air Canada, multiples
Tues 7/28 Air Canada, multiples
Mon 7/27 Air Canada, long connections again
Sun 7/26 Air Canada, multiples
Sat 7/25 Air Canada, long connections again
Wed 7/22 Air Canada, multiples
Tues 7/21 United through IAH with multiple choices (yesterday there was a great 1 stop choice through IAH)
Mon 7/20 United but really long connections
and then nothing before that
editing to add: And some flights say 4 seats left, or 3 seats left, or 2 seats left. Some don't say anything so I assume they'd work if I needed 3 like you do.
