I have sent you the updated times / schedule for the return flight on monday, and this afternoon the airline have officially confirmed the new flight times for the outbound flight to Switzerland also.
The up to date flight details are:
AIRLINE REFERENCE: ENNLZ55
No luggage pre booked.
The flight is now about 1hour earlier then the original flight quoted, and going from Stansted instead of Southend on the outbound. On the return flight, it is going back to Stansted instead of Southend, and the times are very similar.
The distance to Stansted is actually 5 miles less then Southend airport, so it should be a shorter drive for the parents.
