It has gotten better over the last 2 years, in my experience. of course, EES and ETIAS starting may make it worse again, even if only temporarily
It will definitely make things worse temporarily but it should get things approximately back to where they were before brexit. Once the new system has bedded in British people will only need fingerprinting if they have never used EES or they haven't entered Schengen in previous three years or have a new passport. This hassle should be offset by quicker processing of third country nationals that don't require visas e.g. American, Canadian and Japanese tourists.
UK Electronic Travel Authorisation roll out has four stages:
1) Qataris were the launch nationality in November 2023
2) Other GCC nationals + Jordanians joined them February 2024
3) every non european who doesn’t require a visa (unspecified date late this year)
4) EU/EEA citizens in spring 2025.
Eurostar in Paris, Brussels, Lille and Amsterdam should benefit from the staged approach of UK.
Leasing Benugo for space for extra EES enrollment kiosks is a smart move.
