I recently traveled through the frontier terminal las vegas (LAS) on my way to Canada for a vacation, and I have to say, my experience was quite smooth. The terminal was well-organized and clean, which made navigating through it relatively easy. The staff were friendly and efficient, which helped in getting through security and to my gate without any hassle. https://jumbojourney.com/frontier-airlines/las-terminal-harry-reid-international-airport/
