Narrative: Since I have been flying [a] turboprop and not the jet for years and never with this mainline carrier; I asked the other FA some questions; especially about service and the life vest since it was the first day of Extended Overwater (EOW). There was less than 30 minutes to prepare and board. It was a quick flight; 20 minutes.Departure and inflight went well.We landed. After we stopped at the gate and the Captain turned off the seat belt sign; I released my seat belt and turned the lights on. I watched out the window; and when I saw the ramp outside the plane; I picked up the interphone and made the announcement 'Prepare doors for arrival' I then lifted the handle instead of the cover. Before I could correct the handle blew out of my hands. When I saw what happened; I immediately told the Captain and then the other FA. The door stopped because of the ramp. The passengers were deplaned through the 2L door with stairs.I sat hot [reserve] the day prior. The next day I was on LCR [Long Call Reserve]. Scheduling called to assign me a trip with a show 12 hours later. I did not get the full schedule because I was sleeping; but had her repeat the show time. I tried to go back to sleep for a while. The flight was scheduled to arrive [late at night] XA:00. After several calls to the hotel and waiting for the van; I arrived past XB:00. I was told by the desk clerk that they did not have a reservation for me and he didn't think he had any rooms available. After talking with scheduling; finding a room and getting to the room it was past XC:00. I was also told by the clerk that I did not need to reserve a van; just come down. I was ready and waiting for the van at XM:30; but when the driver showed; he said he only went at the top of the hour. We waited for another airline crew who were late. Then traffic. Not much time left to get to the gate. However; I still arrived at the gate on time. At the gate; they did not have me listed on any paperwork. This left a stressful situation and little time to prepare the flight when it was already boarding time.Perhaps; because of all the variables that can go wrong causing stress and fatigue such as time zone changes; time constraints; missed communications and dependence on others; there could be a better use of reserves. Maybe; more of a time buffer using reserves or pull reserves from the originating flight base or a closer base.Even though I trained for both the turboprop and the ERJ; the aircraft are very different including chimes; lights; announcements; service; code share procedures; evacuations; and door operations. Hands on and visuals need to happen. Since we will soon be on one type of aircraft; hopefully this will correct.


Second narrative: I was working in the back. After disarm announcement was made; I disarmed and made cross check announcement. In a few minutes I learned the slide had blown. We deplaned out of L2 door a few minutes later.I think that either online training or hands on training is needed for those who have flown only the turboprop for quite some time. Many FA being displaced from closing bases and the operations are so different with the doors. Habit takes over and practice is needed.


Synopsis: EMB175 Flight Attendants reported an inadvertent slide deployment during gate arrival. Lack of hands on training was cited as a factor due to the EMB175 being new equipment for the airline.
