I just found out you can book flights on Tuesday afternoons for way less | Budget Travel Hacks - Freelance Forum - The Community for Independent Professionals
My buddy in Atlanta swears by checking prices right after midnight on Wednesday, when their system updates. He says it's less about a specific day and more about catching those automated price refreshes before anyone else is looking. I've had some luck clearing my cookies or using a private browser too, because sometimes they hike prices if they see you searching the same route over and over. It feels like a weird game you have to play just to get a normal fare.
Yeah, the cookie thing is real. Sites track your searches and can bump up the price if they see you're interested. I always use incognito mode now for any travel search. It's annoying but it does seem to stop some of that fake urgency.
