Trying to gauge my likelihood of making it onto the jumpseat of the 190 in a few days. Looked through a couple pages of the forum but couldn’t find anything regarding the load numbers and how they correlate. Currently the stand by list is showing 7 listed, with a CORE of 2 available seats, however when I check seats in the app, there are over 15 seats open. What does core mean? Thanks in advance, new to commuting on b6.
