Last I heard it was 767's BWI-LGW to take advantage of SWA feed in BWI. I requested an interview in August and they replied all their interview slots were filled. (At the time I was a current 767 PIC/transatlantic.) Hadn't heard anything since.
Got some information that most of the interviewees were current and relatively young Delta 767 captains who were going to bail out of Delta to get their lump sum retirement before they lose the option. I guess the soon-to-be millionaires needed something to do in their free time, so they decided en masse to grab jobs from those who lost their retirement and might really need them.
