I read somewhere recently that the NYC-TLV market was one of the most underserved international markets in the country because about 250k passengers book a one-stop option. UA may very well be trying to make EWR-TLV more O&D and shift the connecting traffic to IAD. I could easily see this route going daily within a year or see ORD-TLV being added on alternate days, giving UA 4x flights everyday.
