Flew with them post 911 to Miami and have to say it was the best service we've ever had (could be airlines were hurting at that time) . Again in 2006 to Germany and service was proper as well as keeping schedules. A year or so we flew with them to Cuba, but was a packaged deal (we found the service a bit more herded.. and not personalized as before) But again, it was a charter - not sure it that means anything or not.
Overall - on time, no lost luggage, friendly service for the most part and seats are a tiny bit more roomy than WestJet.
