I posted most of this on another thread, but I decided having its own thread would make it easier for people to see my experiences at resuming international travel.
Myself, my wife, my sister-in-law, my niece and my niece's friend (I designated the trip my Charlie's Angels trip) decided to proceed with our Jamaica trip to an all-inclusive resort, that we had planned a year ago. All five of us were fully vaccinated.
We flew in on American from Tucson, with a stop in Dallas. Entry to Jamaica required completing an application online, agreeing to stay in the “Hotel Zone”, use only authorized transportation, stay at an approved hotel, and get an approved COVID test, with negative results within 72 hours of arrival. We passed all of these requirements. Upon checkin for our flight the agent checked mine and my wife’s COVID test result, but no one looked at the results of the other three people in our party. No one at American or TSA looked at anything else besides a passport and boarding pass. American has a strict masking policy that requires a proper mask be worn properly for the entire trip with the exception of short times when you might be eating or drinking something. Once on the flight to Jamaica we had to fill out a form that asked questions similar to the online form. Upon arrival in Jamaica and working our way through customs and baggage claim we had our temperatures checked and we were applied with mandatory hand sanitizer several times. When we handed the customs agent the form we filled out on the plane, I don’t know if she compared it to our online form or not. All went very smoothly.
At our resort we got the required COVID test for our return to the states( our 4th ones - you never get used to the cotton swab stroking your brain via your nasal passage ). Our results were available the following morning in the lobby of our building. The COVID test results were examined by the agent at the airport prior to issuing our boarding pass.

In addition, we had to fill out a ‘Passenger Disclosure and Attestation to the United States of America’ form that we turned in at the gate just prior to boarding. The form simply asks, ‘I attest that I have received a negative pre-departure test result for COVID ... during the 3 calendar days before departure’. Then you sign and date it.
At the resort they have implemented a lot of COVID protocols:
a) they clean everything often
b) masks are required for entry into restaurants, or when at a bar, but not at the beach or when actually eating or drinking
c) the staff wear masks all the time
d) buffets are done by the staff dishing the food you desire, no self serve
e) some restaurants are closed on a daily, rotating basis - a COVID concession
e) some aspects of the spa weren’t open, but most were
Beach, sea, and pools were great, as were the drinks and food. It’s an all-inclusive resort.
When reaching the states, in Dallas, everything proceeded as the return from any international trip, if you ignore the masking and social distancing.
**Even with all of the required testing and protocols I assess the week as a successful reentry into international travel. **
Hopefully, as time passes, international travel will return, little-by-little, to a less restrictive activity closer to what it was prior to the pandemic.
Hopefully this provides a few insights to people wondering what international travel might entail.
