I’m in JFK waiting for my connecting flight to Dubrovnik for the tour that begins on the 26th. When I checked into my first flight in Boston, the Delta agent wanted to see proof of my negative COVID test. She hadn’t read that Croatia would accept either a negative test OR proof of complete vaccination fewer than 270 days prior. Fortunately, I had both (being a belt and suspenders kind of person). She did recognize it eventually —after I told her and she kept reading the requirements — that either would be sufficient. She also asked for the Croatia entry form, so — a word to the wise: if you’re planning to take this trip soon, do fill out the form from the link in the digital green book.
