Unfortunately the current waiver for Delta is only up to June 15th. I'm booked on June 21st. They've been schedule changing the flight, moving my departure time up by about half an hour each time, and it has happened twice already making it more and more inconvenient for me. It's a Basic ticket, so I can't just cancel it, but if they move it up again, I might just bite the bullet and abandon it and book myself a new flight out of JFK or LGA
