Our flight August 9 Luton-Newark was just cancelled. They booked us on a flight the following day which does not work for us. I'm trying to get a refund but there is no customer service available on weekends (I was given an email address to write to and told someone will get back to me in two days). I'd avoid the hassle, knowing what I know now. I'm sure if we had got on the flight it would have been great but to me the most important thing is reliability. I have seen people posting about August 7 cancellations as well -- just too unpredictable.
