So now that AA & DL have released their summer 2019 European schedules, when does UA release theirs? AA made a bigger splash than DL, but that was mostly adding destinations UA already serves with the exception of BLQ & DBV. OPO kind of came out of nowhere this past year, but it is a *A mini-hub with TAP and there isn't any LCC flying OPO-USA. With that in mind, I do think Croatia is a possibility, but I think VIE-EWR, ATH-IAD, MXP-IAD, and WAW-EWR are also strong candidates.
