My plane experienced a 2-hour delay last weekend, holding me up on my travels & already making me quite miserable. The lobby of the airline was crowded, the food was terrible, the bathrooms were disgusting, & the seats were uncomfortable. The heating in the building also left something to be desired, with that something being actual overheated air. Their Heating, Ventilation, & A/C either wasn’t honestly effective or wasn’t set to run high enough to matter. Travelling is stressful enough already, thanks to the conditions of the airlines & the fear of delays, layovers, & cancellations, & I was highly irritated by the whole experience, then when the plane I was waiting for finally arrived I was among the last to be boarded because of my ticket number & was placed in the honestly end of the tail part of the plane, then unlike the lobby, the aircraft was rather warm, so I attempted to redirect the vent above me to blow the cool air directly on me, however nothing happened. The slots of the vent were open & yet no air was blowing out, & briefly passing my hand over the vent beside me proved the air was on; I got ahold of a flight attendant to request a seat with a functioning air conditioner vent although he couldn’t move. I could clearly see some sections had an open seat in the row however I was not permitted to change seats to have a functioning A/C vent. The best they could offer, which reflects rather poorly on them in my opinion, was a miniature cup of ice water. I was left to do my best putting up with everything until I managed to fall asleep. I’ll be looking for a better airline next time because the inconveniences I faced were too insane to let slide.
