Originally scheduled to switch from the 77L to the 744 with newly installed 180 lie flats on March 23, the switch will now happen on April 11.

I intentionally booked a flight through ATL onto BKK so that I can experience the new 180 degree lie flat 744 for April 4. Now, its on a 77L

I wonder if DL will let me switch to the non-stop out of JFK - NRT so that I can at least stick with the 744??
