Well the good news is that they can land planes without engines, gliding in over the Atlantic Ocean onto tiny Azores islands without functioning navigation equipment. The bad news is that they have to occasionally do this.
Let's see, I have had several delays with Air Transat, each time because of "technical problems" Air transat has had several engine fires on their planes and they have left airports one hour ahead of the scheduled time leaving passengers stranded.
But heck, I was scheduled to fly on the Air France flight that crashed in TO and last minute was switched to another flight, so Air Transat looks pretty good now.
