Just booked a few flights recently -
2 RT Tickets on AA for in J LAX-ORD - still was under the 50% bonus with Amex Biz so all in was 50K points after the rebate.
2 RT Tickets on Delta in J LAX-CUN - still was under the 50% bonus with Amex Biz so all in was 62K points after the rebate.
2 RT Tickets on ANA in F LAX-NRT - Helped my parents book this and helping them with an itinerary in Japan similar to what we did for our honeymoon. They have a ton of Amex MR and wanted the additional flexibility of more times booking straight with ANA so they transferred 300K MR to ANA to book. Helped them transfer a bunch of Chase UR to Hyatt and get them in the Andaz while in Tokyo.
