Europe is full of economy and discount air carriers. Almost every major city has a reliable and affordable airline connecting it to other countries. Yesterday we flew up from Lisbon, Portugal to London on easyJet. easyJet links about 130 European destinations with cheap and reliable jet service. They have been in business for 11 years and have a fleet of 111 Airbus jets, all for which are 3 or less years old. Our flight yesterday took us about 3 hours and cost about $60 per person! This is unbeatable. Now-a-days it makes no sense to travel by rail or car. Fly instead!
