PARIS AIR SHOW visitors should be warned that Eurostar is not operating on the Folkestone ” London stretch on Sunday 15 June, that is the opening (and very much) public day. This is due to vital work that has to be done in integrating the existing tunnel operation with the new high speed Kentish track. If you are booked on that day speak to Eurostar who will happily re-organise your ticket. http://www.eurostar.com
