TLV - Barcelona el al 20k qantas economy 9am to 12pmish
Barcelona - EWR 6pm to 9pm Norwegian premium (not business as this is the 787 not the chartered a340) $599 i think
norwegian also has a tlv - barcelona with better timing for connection but is more expensive
norwegian flies direct to nyc from around 6 european countries ( athens, barcelona, cdg, london, copenhagen forgot other one) so there are many possible options, although not so many on 10/23 from what i searched
