I have not flown WN in several years, so have a couple of questions about EB purchase. It does cover all legs on a flight with connections, right? My upcoming flt is one short leg and one very long leg so thinking EB would be worthwhile for the 3+ hr leg. And does WN still just board all A's as a group, then B, etc or do they now go sequentially with each group? (a1, a2, a3 etc)
