Timatic was designed for internal use by airline staff, using software in the pre DOS and early DOS years, and was largely focused on visa requirements - can a Greek citizen with a transfer through Italy and go to the USA without a visa fpr Italy or USA? It has been adapted for the pandemic, and there have long been passenger usable screens such as that used by United and SkyTeam. But I don't think anyone would claim it is perfect, and it is often slow to be updated. The reason being that countries are typically forgetting or not bothering to inform ICAO, the international body for aviation at government level. And it's easy to see why that happens. In the UK, which is keeping ICAO updated, the usual process is the Home Office decides who can enter, they tell the Department for Transport, and they tell ICAO. This happens perhaps 4 times a year. In the Pandemic, the Department for Health and Social Care will make an annoucment, at the very last moment, sometimes in the early hours of the weekend, a Statutory Instrument will appear with the details. This Statutory Instrument then gets amended a dozen times, perhaps to reduce restrictions on some obscure group of crtical workers who travel a lot.

Sherpa has a reasonably useful front end, is clearly pandemic related. It also splits off the sections in a sensible way and critically gives the source of the information and the update date. Which then allows people to find the government website concerned. So if you imagine all the queries we see in this forum and in the main Coronavirus forums as to "I'm doing X, what do I need to do?" - and then add in all the calls that the BA Contact Centres must be getting - you can see the need for this. I have noticed some mistakes, but it's such a fast moving situation I'm not sure whether it's me or Sherpa that is mistaken!
