Aircraft arrived at ZZZ Gate X1. When we arrived on the aircraft; it was extremely hot and felt like no air was flowing. I proceeded to stow my bags and completed the pre-flight check of the aft. At that point my face was severely flushed and got an instant headache. The CA (Captain) was aware of the heat and asked for external air to be hooked up. It was not cooling the aircraft at all. He then requested that the external air unit to be switched out for another. The temperature in the FD (Flight Deck) was 98 degrees and the cabin was about 83 degrees. We waited about 45 mins and at that time the forward cabin began to cool down but the aft was still extremely hot. The CA suggested that we give it more time. My flying partner then reached out to management. We both called CS (Customer Service) and asked to speak to a MOD (Manager On Duty) to inform them of the situation. Unfortunately; the MOD could not be reached because [the MOD] was driving and would return our calls when possible. However; [the MOD] failed to contact either of us. After that the CA came out on the jet bridge and asked if I can sit in the extra jump seat while he can move passengers towards front of aircraft so that last 3 rows remained unoccupied. He was told no and continued to talk to dispatch at that time. The CA suggested to dispatch that we take the broken aircraft at gate X11. That aircraft was being worked on but dispatch said no we could not swap to that aircraft. We waited a little while longer and then CA said the aircraft was cooling down and we can board once the cabin temperature was below 34 degrees. So at that time he wanted to board. I then got back on the aircraft and headed to the aft position. It was still very hot and felt like no air was circulating. The CA was asked what would happen when we disconnect the air and passengers are boarded creating body heat in the cabin? He said it would be fine once the aircraft started moving. I was not comfortable with that but the CA insisted that the cabin would cool down. He then asked if we could board and I told him to ask [Flight Attendant B] since she was [the] forward position. The air was [then] disconnected and boarding commenced. The temperature started rising again in the cabin and I felt dizzy and nauseous; my head was throbbing; I felt as if I couldn't breathe; and I was really hot and flushed. I felt as if I was about to fall. I held on to the seat back at which point I grabbed the interphone and called [Flight Attendant B] telling her I felt that I was about to pass out. She immediately stopped boarding and made her way back to me. [Flight Attendant B] and I made our way to the extra FA (Flight Attendant) jump seat since there was quite a few passengers onboard the aircraft. [Flight Attendant B] gave me water and ice on my face trying to cool me down. The boarding process was stopped. I sat in the jump seat for a little while until the passengers were deplaned and returned to the gate. I was then moved to a passenger seat. The EMT was called. They asked a few questions and took my vitals. They asked if I was drinking enough fluids which I said yes and if I still felt dizzy but I wasn't at that time since I [was] seated and reclined in 1C. I was asked if I needed the paramedics and [to] be hospitalized but I said no. When the aircraft arrived in ZZZ; we were told the pack was broken and that it wasn't cooling down. The temperature inside the aircraft was extremely hot. CA said that he would try and get the cabin to the temperature needed for boarding. The CA knew of the conditions on this aircraft because he had worked on it the day prior and the pack was MEL. The temperature on this aircraft was just extreme.
Aircraft came in to ZZZ. When I walked on the aircraft it was extremely hot. The other crew members came on and experienced the same thing. Our Captain asked for an external air cart to be hooked up. That wasn't working so he asked for a [new] cart to be hooked up; he [said] the cabin temperature was 83 degrees and the FO (First Officer) said the flight deck was 98 degrees. While the Captain called Dispatch; myself and the other Flight Attendant stood on the jet bridge since it was so hot on the aircraft. We were told that there are no aircraft(s) to swap with and to let the aircraft cool down. After a few minutes the Captain realized that the air wasn't circulating in the cabin; so he asked the [ramp crew] to hook a different cart up. We waited at least 45 mins; it got cool in the forward cabin; but the aft was extremely hot. The aft just wasn't getting cool. The Captain came on the jet bridge and said he had a few options at this time I'm on hold with crew scheduling to see what advice the MOD (Manager On Duty) can give to myself and flying partner; but I was told that she was driving and will call me directly [yet] still no call. A few of the options the Captain had were the aft FA (Flight Attendant) sit in the extra jump seat. I told him no; she can't sit there; then he said move all passengers from the last 3 rows since that's the area that won't cool down. The Captain told us that the cabin is now cool and we can fly once the temperature is around 34 degrees in the cabin. 	When we get back on the flight; the aft FA said it's still hot in the back. So I asked the Captain what will happen when the air is turned off and passengers are on the plane will we have the same situation? He said no; it should be cool once we start moving. When the boarding process started; the air was turned off and the cabin started to get hot; [Flight Attendant A] then called me on the inter phone and said she felt like she going to pass out. When I looked in the cabin she was holding onto the seat and leaning over. I stopped boarding and ask the FO to watch the passengers at the door. I went and brought [Flight Attendant A] forward and placed her to sit in the extra FA jump seat. I placed ice on her face and gave her water to drink. I then deplaned the aircraft and told the passengers on the jet bridge to go back to the gate; I then messaged the gate agent and called my Base Manager. [Base Manager] made some phone calls and was touching base with me the entire time. The paramedics were called for [Flight Attendant A] and two [company] managers came on board. When [company managers] arrived they made a comment 'you ladies are so lucky to have AC' and laughed. The air was just turned back on at that time. I told them if the air is off; the cabin is completely hot. [Manager A] sat on the aircraft while [Manager B] left. A gentleman came on; he never identified himself nor did he speak to us. He check the air vents and left. I try to explain to him when the air is off the cabin is unbearable. The flight was re-crewed and [Flight Attendant A] and I dead headed to ZZZ1.[I] called Scheduling and Base Manager. The sad thing about this [was] the on-call manager never called us that night to ask what occurred and how can we be helped. I was told she would call me directly. If this was more critical who would've helped? I'm grateful that [Base Manager] assisted and kept in touch with.Management on-call should be responsive to calls and held to the same standards flight attendants are held; while on-call. The company needs to have maintenance look at all aircraft that have these issues since there is a rise in these complaints.
CRJ-900 cabin crew reported extreme heat in cabin due to inoperative pack.
