okay so i just landed at denver international and honestly im still kinda vibrating from the whole experience and i just had to hop on here and vent a little bit and maybe give some actual real talk advice because its a really tricky airport and if you dont plan it right you are literally going to miss your flight and that would be a complete nightmare and nobody wants that especially not after the hell that is modern air travel right.
denver airport or den as the locals call it is basically its own little city out in the middle of nowhere and it just sucks up time like a sponge and you think you have enough time but then suddenly you dont and youre sprinting for your gate feeling like youre in some sort of bad movie and ive done that too many times to count but ive finally gotten smart about it and im sharing my secrets now.
When I actually show up
so after years of stress and almost missing flights and literally having heart palpitations trying to make it from the rental car center to the train to concourse c in like twenty minutes which is basically impossible ive figured out what works for me and its not for the faint of heart but its what i recomended if you want to be chill for once and not utterly lose your mind.
-
quick domestic hop (just a carry-on, maybe checking one bag, not a busy time of day): honestly even for a quick domestic flight with just a carry-on and lets say its a tuesday morning at like 9 am which isnt peak chaos but still has some folks around i usually try to get to the airport itself and by airport i mean pulling up to the curb or getting off the rental car shuttle like at least two full hours before my boarding time and not my departure time because boarding is when they close the doors and you want to be sitting comfortably at your gate maybe even thirty minutes before boarding starts and thats just smart planning right.
-
holiday travel or international flight (checking bags, peak times, anything stressful): oh my god if its thanksgiving or christmas or god forbid spring break and youre going international and need to check bags and deal with customs paperwork and all that jazz you need to add like another hour or even an hour and a half to that initial two hours so were talking at least three and a half maybe even four hours before your departure time and people will look at you like youre crazy but when they are stuck in the security line behind a hundred other desperate souls youre going to be sipping your overpriced coffee at the gate and feeling smug and thats a good feeling trust me.
What messes up your schedule
there are so many things at den that can completely throw off your timing and its not always just tsa lines which are usually the big one but its a combination of a bunch of little things that just add up and make you wanna pull your hair out and scream.
-
tsa lines: this is the obvious one and it varies wildly but the south security checkpoint is often the longest and the west security checkpoint sometimes feels shorter but its a gamble and the clear and precheck lines are usually fast but even they can back up when its super busy so dont rely on them being a complete free pass every single time.
-
parking and rental car shuttles: it takes a surprising amount of time to park or get on the rental car shuttle and then for the shuttle to actually get to the main terminal building and its just a time sink you dont account for and suddenly ten or fifteen minutes are gone just like that.
-
bag drop lines: if youre checking a bag even if you checked in online the bag drop lines can be horrendous especially with certain airlines that always seem understaffed and you can wait twenty minutes or more just to hand off your luggage and that adds to the stress.
-
the train to concourses: once you get through security you still have to take the train to concourse a b or c and those trains while generally efficient can get crowded and if you just miss one youre waiting a couple minutes for the next one and then it has to actually get to your concourse and its all just more time adding up.
-
denver weather: this one is huge because denver weather is literally insane and can change in a minute and if theres a sudden blizzard or even just heavy snow or high winds it can cause delays on the roads leading to the airport and even inside the airport itself and then flights get delayed or canceled but just getting there can be a nightmare too.
-
random construction or terminal issues: den always seems to have some sort of construction going on or some random system issue and it can affect everything from check-in kiosks to security checkpoints and its just another unpredictable variable you have to account for.
so basically just dont mess around with den and give yourself way more time than you think you need and its always better to be early and bored at your gate than frantic and sweating through your shirt hoping they still let you on the plane because seriously its just not worth the stress and thats my honest opinion after way too many den airport adventures.
