Continual frustration...
Been looking for a few months for last 2 weeks in August. 3 people. From NYC, pretty much anywhere in Africa (Tanzania, SA, Moz, Madagascar), Asia (Korea, Malaysia, Indonesia, Mongolia), or Brazil. Nothing. We used to be much less flexible and book for 4, and never had as much trouble.
Asia is pretty much impossible right now. Many routes that used to have tons of availability have disappeared - HGK, ICN used to be wide open and now nothing, PEK has no direct service still, which pretty much just leaves TYO. Ethiopian only releases 2 seats.
Never seen it this tough in all the years.
