A British Airways informa:
“A simple way to understand entry requirements
We’re pleased to inform you that we have launched a new feature on ba.com which allows passengers to quickly and easily check entry requirements by country. Sherpa returns requirements for both direct and indirect trips, making it a valuable tool for customers wishing to transfer via London as well as those whose journey is point-to-point. It will return COVID-19 test requirements, quarantine protocols and entry restrictions for anywhere in the world. Sherpa also helps passengers to understand and apply for certain eVisas.
Please feel free to direct customers to the Sherpa site and remind them requirements could change so to keep up to date right up to their date of departure. A link has also been added to the British Airways Trade Support site for your convenience.
We are committed to making travel as smooth and frictionless as possible and hope this will make understanding requirements for travel much simpler for you and your customers.
