I did it as recently as last December from IAH-AMS, but it was more comfortable than BF in my mind. That was because I brought my Therm-a-rest Prolite 3S, which weighs all of 13ozs. and folds up to less than a half gallon carton of milk. That took care of all the protrusions and humps between the seats. A true lie-flat, which BF does not have.
