We made a decision about 15 years ago that we would not stop flying altogether- but would never fly short distance when train is available (like Switzerland to UK, or Italy, Austria, Slovenia, etc) and would only fly into further European destinations never for less than 1 week- and long distance only for 3 weeks min.
Not flown now for 2 years because of Emma the dog, whom we adopted aged 13 and cannot be left in kennels- so we drive currently- and try and give lifts to friends or youngsters who otherwise wouldn't be able to go.
Is there such a thing as delicious ready meals?
