ORD has some pretty good 787 flying (no 777 currently). Apparently the economics of the 78 are excellent for ORD-Euro flying and they are planning on significant expansion once the new terminals come online (with more WB gates).
As I’m sure you know, plans are worth about the cost of the paper they are printed on in this business.

WB flying is awesome. Is it so awesome you should give up 3 years of seniority at a career destination where you are already driving to work… 🤷‍♂️
