Eurostar has told passengers using its trains to Paris not to travel until at least 3 April dueto ongoing industrial action by French customsatGare du Nord station in Paris.
There have been queues of up to six hours for passengers departing the French capital amid major delays and train cancellations, prompting some holidaymakers to wonder if this is a taste of travel to the EU this summer if there is a no-deal Brexit.
French customs' officers are asking for higher pay, better working conditions and more staff to cope when Britain leaves the European Union. Since earlier this month checks on passengers have become much more rigorous than previous methods, to highlight, according to French union leaders, the lack of preparedness for Brexit.
Instead, the train company is offering anyone travelling up to 3 April a full refund or a free change to travel at a later date.
Anyone hoping to still travel from London to Paris this weekend by plane instead is going to have to dig deep. When we looked, last minute British Airways' flights from London Heathrow to Charles de Gaulle travelling out on Friday evening and returning on Sunday evening were £772 per person and upwards. And Air France's flights from Paris to London on Sunday were all full after lunchtime.
Alicante airport in southern Spain would need the staff and resources to deal with an estimated additional 201 hours of immigration checks on British passport holders, on average, every single day.
The European Tourism Association (Etoa) has estimated that additional checks could add an extra 90 seconds for each UK passport holder. To put that in context, it would take a single passport lane an extra 17,010 seconds - nearly five hours - to process the 189 passengers on a single Ryanair flight,if all those passengers were UK passport holders.
