Saudia often has 7 or more business class award seats
open on a single flight, and availability like that seems to be the norm for most of their long haul flights.
Here's another ExpertFlyer screenshot showing 4 First Class and a minimum of 7 Business Class awards
available on a single flight from Santiago and Miami:
-LSB-...] Virgin Australia award space is widely available for up to 12
people on a single flight, including over peak times like Christmas and New Year's.
As opposed to economy where you might find 6 award
seats on a single flight, there's a dearth of availability on Delta in business class.
You're not going to find more than 2 first class awards
on a single flight, except on some anomalous routes like Singapore — India and Singapore — China.
It can be tough to find two first class award seats
on a single flight to Asia nowadays, let alone 4 - 5 seats, enough for a family.
