Flybe airlines is a very inexpensive way to fly around Europe. My flight was from Edinbaugh, Scotland to Southampton, England. Flights are on small planes but the service is excellent. We flew in a turbo jet where you entered the plane on ground level and climbed the stairs (5 or 6 stairs) to reach the cabin level where the steward welcomes you and helps get you seated. Our fight lasted about an hour. We flew low enough where the landscape was always in sight which was a treat.
Flybe has flights all over the United Kingdom, Austria, Belgium, Bulgaria, Czech Republic, France, Germany, Hungry, Ireland, Italy, Luxembourg, Netherlands, Poland, Portugal, and Spain. It is a great way to hop around Europe.
Many airports have lounges for Flybe passengers and airport assistance is always available.
