My friend Linda ( who worked at the pentagon for many years) Has not flown since 9/11.
Since then she nad her husband have visited Italy every year. Shae been in Autria, Germany, France, Spain, Portugal, the UK, Autralia andmany Islands in the Caribbean as well as the Azores, Madeira and Santorini.
They have also cruised withus to the Mexican Riviera a well as Alsaka.
They have also cruised with us on the Oasis back in april.
They drive across the the US and Europe, they take trains and do many cruises, but they will not fly.
So if you have the time and the money, you can travel extensively without flying.
