LH (Lufthansa) - very good for families. They go beyond to seat family together. Last month we did Singapore to FRA on a 95% full flight, and all 4 of us sat in 4 center seats.
SAS - gate agent goes beyond, if talk to
KLM - easy and many destinations, but agents not that flexible
AF - great experince
AC (Air Canada) - one of best in my opinion. Select your seats 24h prior. We did Asia in March from DCA-YYZ-HND. Last year Beijing from YVR-PEK. Always able to select seats yourself.
EK (Emirates) - great airline, great movies. Seat families together. Could check-in 24h prior at kiosk. Looking at smiley faces more than 72h ahead of dep is no indication, since thats when even their own employees can check loads.
Finnair - will upgrade to Business.
AZ - (Alitalia) - good experience on flight from JNB-FMC
OS (Austrian) - Great experience
Iceland Air - things can get hectik in KEF on busy/delayed day (due to bad weather. But gate agents are workable.
VS (Virgin Atlantic) - best phone support for checking loads prior. Btw, BA was the worst phone experience (when we used to have them, not anymore)
LX (Swiss) = Swiss quality

We haven't flown on LOT, Iberia, AirItaly yet.

LATAM is great for South America.
SAA great for South Africa (have to email pass bureau 2 weeks in advance.
Kenya Airways great for Africa
Etihad good back-up out of UAE should EK plans not work out. Can rent Hertz in Dubai to get to AbuDhabi without getting charged one-way fee.
There are at least 40 more (some obscure) airlines on our ZED.

Remember: beyond US border they call it Staff Travel, not Non-Rev.

Planing to do Quantas in Feb 2020. Anyone with non-rev experience?

Travel while you can. Life is shorter than you think.
