We have Capital One, Amex, AA, Delta, Bonvoy, & Chase points, and (2 adults) are looking to go to TLV June 30 for a week, and then spend a few days in Tuscany before heading back to JFk. Ideally, we'd like to use miles, but are having trouble figuring the best use of the points/partners/conversions. Most United flights (<12 hour flights) are >90,000 points one way.
Any help on best conversions to airline partners that would be the least & best use of points is appreciated...
