Has anyone noticed the serious deterioration of the service operated by Silver Airways between Parkersburg and Cleveland? When Silver Airways began, there was a great improvement in reliability and enplanements were trending upward but that has been seriously eroded this year. I began writing this letter on Tuesday Nov. 12. The 6 a.m. flight from Parkersburg was two hours late, the 9:50 a.m. was an hour and a half late, the 1:25 p.m. was almost five hours late, the 5:25 p.m. was 2 minutes early (!) and the 9 p.m. from Cleveland was almost four hours late. And Tuesday's pattern has been repeated many times this year. When it's bad, it's very, very bad. But when it's good, it's very good: today, Wednesday, the flights were on time or early. But the variability in reliability means fewer and fewer passengers are going to trust the operation.
