I learned about Allegiant’s booking window the hard way. Last year, I tried to plan a summer trip to Florida in January, but the dates I wanted weren’t even on the site yet. Turns out Allegiant usually opens schedules only about 6–9 months in advance, and sometimes they release them in chunks. I ended up checking back every couple of weeks until flights finally popped up. When I needed to adjust my return date later, I just called 844-734-0813 and it was way faster than wrestling with the website—they handled the change in minutes. My advice: if you don’t see the dates yet, don’t panic, just keep an eye on the schedule releases. And if you need to book, cancel, or tweak anything, that number saves a ton of stress.
