We have some unusual flights due to the incredible high prices for our origin city, Cincinnati. It leaves us staying a few nights in NYC and departing from Newark on Jet Blue late morning. .

Question is this. We will not have checked bags but need to check in since it is an international flight. Are going to find a long line at Jet Blue just to prove EHAS info or is it a pretty quick situation? I can't imagine a Sunday 11:00 AM flight being a crowded time at the airport but we have zero experience with low cost air travel much less EWR.

FYI, Cincy to SXM was about $1200. By mixing and matching our cost is about $700 so our two night stay in NY is free.
