Thank you I am looking to find something for next week.
Iberia seems to have good pricing on flights from LHR to BGI in Barbados (operated by BA), but according to
https://www.visitbarbados.org/covid-...uidelines-2020 there's still a 5 day hotel quarantine once in BGI, in order to wait for a mandatory second PCR test after arrival there.
This would be my least favorite option as I'd be paying 5 nights at the hotel + separate flight from BGI to NAS, either via Jamaica (KIN) or Turks & Caicos Providenciales (PLS) - there's no direct options from BGI to NAS.
Ideal solution would be anywhere in Europe -> Jamaica (no quarantine) -> Nassau
Getting closer to a solution thanks to your help. really appreciate it.
