I have had several inquiries about how Covid-19 affects the delivery of your QSL cards. It is a fluid situation and after taking advice from Royal Mail i can inform you that posting from the UK is continuing as normal.
Nearly all mail is sorted by machine so is not touched by human hands. Large mailings are bagged from here and sent directly to London Heathrow Distribution Centre and the bags put on onward flights to the destination country. Remember many flights are cancelled and this can also add to delays.
Royal Mail has a page on the website updated for “International Incident Bulletins” this link will take you to the page so that you can see what restrictions are in your country and where delays may apply.
Updated 24/03/2014 – As air flights around the world reduce very significantly to avoid the spread of Covid-19. This has a knock on effect on a restriction of air freight available to send post around the world. International Post WILL be more expensive and will also experience delays as most flights are not available to carry mail.
