http://www.dansdeals.com/archives/71765I was on this flight
Previously booked with a stopover on AC, but while looking around the UA site, I noticed this flight. I knew it was strange so I called the call back number to see what is was and was told that yes, we have 3 flights a day from TLV, always. Still didnt jive since I never heard of that, and even though I'm no expert the flight number was strange to me. so I looked at DD and found Dans post!
I could have booked Biz but I saw that the seats were so empty I could probably get a row of 3 seats to myself which would allow me to lie down which is not as good but cheaper and good enough.
They charged me $50/ticket for the change fee.
At the airport the checkin was so empty, only 3 counters and half the time the agents had nothing to do.
In the end, biz filled up, but not economy. So I had a row to myself in the back. And the rest of my family also. And lots of other happy flyers.
So it was a great flight and worth the money to change.
