I have a flight ticket from the UK, to Costa Rica, with a connecting flight in Germany (in March). The airline is Lufthansa.
Costa Rica is allowing international travellers in, however, the UK is currently in lockdown and has put out restrictions on leaving your home. The current rules the that UK Government has put out are not very clear:
You can only travel internationally – or within the UK – where you first have a legally permitted reason to leave home. In addition, you should consider the public health advice in the country you are visiting.
If you do need to travel overseas (and are legally permitted to do so, for example, because it is for work), even if you are returning to a place you’ve visited before, you should look at the rules in place at your destination and the Foreign, Commonwealth and Development Office (FCDO) travel advice.
Additionally, the travel info page specific to Costa Rica says:
Commercial flights are not running normally. United Airlines, Iberia, Air France and Lufthansa are operating some flights and other airlines are resuming operations on certain dates. Check with the airlines or a travel agent.
Supposing that these rules are still in place in March, can I travel to Costa Rica for tourism purposes? I cannot find a list of the “legally permitted reasons” anywhere on the GOV website.
