CIBT is the one we use for DL emps. DL has special # but can suggest Haifa, if she still works there.
We have used my miles on KE about 10 yrs ago for business class from ICN to DPS. With 300K between us, I'm not sure they have much value today, which is why many earners call them sky pesos.
Our Brasil trip was weird routing because we were going to Amazonas. ATL/PTY then Copa to Manaus. The Panama Canal part was fun and worthwhile.
We've done one leg on EK to get from JNB/DXB on refundable NR tkts. When possible our buddies use LCCs.
