Soon my family will be making Aliyah, and I will become a frequent traveler to the states for work. I am looking for the best frequent flyer program combining transferable credit card points as well as airline mileage. This will be a ny to tlv flight and being that I will travel frequently I know this is contrary to what we all believe in but can't do stop overs or too many hacks but a non stop flight especially because I will be on a schedule. What's the best airline to go with?
