Just flew LanChile from Santiago to Auckland on a A340. The plane was almost full and this is a long flight (13 hours) across the Pacific. I guess the plane must have been very heavy.

Roll-off took very long and as the front wheel was pulled up nothing happened for a long time. We just sort of 'sat there' until finally, and very slowly, the rear wheels came off the ground too. Maybe this happens all the time but I had never noticed it (and I fly a lot). It normally feels pretty much like one fairly smooth action - front wheels up, nose of the plane comes up, soon after the whole thing is in the air.

Airspeed seemed very low and it took ages to really get any height. I must say I felt rather uncomfortable.

I was just curious as to whether this is normal.
