Until today I hadn't been on one in a while and normally have the "C" seat with no access to the window. Today I moved over to "D" to look outside. We had a long taxi at MSP then directly onto the runway and full power. Flaps were UP. Is this normal? The roll, rotation and climb felt normal; no "mush" after rotation one would expect if this was not normal. Held my breath for a few seconds there.
