Aircraft; Human Factors; Procedure
Aircraft X. ZZZ to ZZZ1. During takeoff right before cruise altitude. Other flight attendant; Name and I noticed a smoky cabin with a burn smell in the front. The Captain was informed. We walked around feeling for hot spots to find the source where the smoke was coming from. The smoke has eventually left. Captain informed us when we were on the ground it had something to do with the rampers disconnecting the hose and the APU which caused the hazy smoke in the cabin.
Flight Attendants reported smoke in the cabin after take off. Smoke dissipated. Captain reported that the ground crew did not disconnect the air start cart supply hose correctly.
