I have Matmid Gold. UA will match me to Premier Gold. I have about 4 rt flights NYC-TLV coming up in the next 12 months plus some domestic flights (United routes). What's best: 1) book my NYC-TLV on EL AL, pay with AMEX Bus Plat and get the 5x miles plus, 2) book on UA and pay with Presidential Plus, and with the flex PQM's I'll probably get up to Premier Platinum by year end, 3) book on UA, pay with Amex (and use the Presidential Plus for other purchases to get the flex miles). Thx
