I am beyond elated by this announcement. TLV has been one of my main destinations over the past 5 years, and it's always been a beating to have to wrestle with AA to get me there from DFW, especially since they just want to stick me on an LY codeshare all the time. It's been getting harder and harder to have AA.com sell me a BA flight ex-LHR, and the BA schedules have not been easy to work with.
Pure speculation, but I bet this goes daily or at least 5x weekly in May 2021.
