During our flight; I noticed what appears to be smoke in the Cockpit. I brought it to the attention of the first officer and jumpseater and immediately followed the memory items for that situation. At the same time the flight attendant called and let us know there was smoke in the cabin also. We informed ATC of the situation. During the decent the smoke began to clear and the smell went away. The Jumpseater looked through the peep hole and said the cabin was clear and the flight Attendant confirmed it went away. We leveled off; run the appropriate QRH and assess the situation. I made the decision to continue after discussing it with the First Officer (FO) and the jumpseater; who was [an experienced] Captain. We informed dispatch and Maintenance and [continued] to our destination with no further incident except for a smell on short final and PACK #2 over heat EICAS message after landing.After landing; I called Maintenance and informed them of what happened. I then wrote it up in the logbook. We speculate it could have been a problem from the PACKs. PACK #1 was MELd and only #2 working. We also briefed the crew that was taking over the Airplane of the situation.
While enroute FL240 and approx. 300 KIAS; both the Captain (CA) and I became aware of a smoke smell; at that time the CA announced 'smoke in cockpit' at which time we both donned our oxygen masks; established communication; then the Flight Attendant (FA) called us at the same time and said there was smoke in the cabin; (we also had a CA on board in the jumpseat he as well donned oxygen mask) I then contacted ATC and made them aware of our situation. At which time we initiated [a] descent with memory items; and shortly after initiating the decent the smell quickly dissipated both in cockpit and cabin. We leveled off and reviewed our situation at which time we (all 3 of us in cockpit) agreed that the cockpit was clear or smoke and smell. At which time we also looked at our position and agreed that our next fix was on the STAR and we would continue to the destination and it was safe to do so. We then reviewed the [checklist] for Smoke/fire in cockpit followed by emergency decent which was then followed by reviewed the QRH; we then contacted ATC resumed our route. The flight proceeded fine until on short final we then smelled an odor again; not a smoke smell more like heater when you first turn it on in the winter which quickly went away. Then while exiting the runway we got a 'Pack 2 ovrht' warning; we continued into gate. We then parked at gate and called dispatch and maintenance and CA wrote Aircraft (AC) up. Then debriefed; walked around AC made a visual inspection; then briefed the crew coming on the AC.
While at flight level 240 the crew of an Embraer EMB145LR became aware of smoke in the cabin.
