I found out by chance 2 days before my flight back from Jfk that they switched to
another plain and I am not on the flight. I had business class ticket.
I was able to contact reservations in Israel and they told me that they moved
me to economy on Delta.
Later they called and said that there is a business class on United but 1 and half day earlier.
I had to take this flight and to lose
many many meetings.
