Two hours late, which for the last flight of the day out of a budget airline isn’t really a delay so much as a scheduling assumption everyone quietly accepts. By the time I cleared the airport I’d missed the bus to where I’d parked the car, so another half hour waiting in the dark for the next one. I was home by half past two in the morning.

I lay down, started to fall asleep, and at half past five my son was standing next to the bed, wide awake and excited to tell me something that couldn’t wait. No window for a nap. That day and the two after it were a mess — mentally, my digestion, my sleep, all three off at once, none of them fully back until the third day.

The Math I Kept Getting Wrong

This wasn’t the first time. It took me a few more before I realized I wasn’t misjudging the flight — I was misjudging everything wrapped around it, the kind of arithmetic that never shows up in generic sleep advice for men our age, because the problem isn’t hygiene or habits, it’s logistics nobody accounts for. A 9pm flight sounds like an evening flight, something you can be in bed not too long after. It isn’t. By the time you’ve cleared the airport, collected a bag, found the car or the bus, you’re closer to eleven than nine, sometimes past midnight if anything goes even slightly wrong, which on a budget airline’s last rotation of the day it often does. A 9am flight sounds civilized for the same reason in reverse. It isn’t, if you live on the wrong side of a city like Budapest, where getting to the airport before eight to be safe can mean leaving before six to clear rush-hour traffic you didn’t think to account for.

Half a Day Gone on a Two-Hour Flight

The trip to Sicily is the clearest example I have. Beautiful place, and the flight itself was barely two hours — but I left home at five in the morning to make it, and between the flight, the airport, and however Mediterranean time actually works once you’re trying to pick up a rental car, it was noon before I was sitting in the driver’s seat. Half a day gone before the holiday had technically started, on a two-hour flight. The way back was worse in the way these things always are, quietly, one small delay compounding into the next until the total doesn’t resemble what any single piece of it looked like on its own — the same slow stacking I ran into writing about why holidays disrupt sleep more than people expect, just triggered by a flight schedule instead of a dinner table.

The Cost That Doesn’t Show Up on the Ticket

None of it was expensive, and that’s the part that stings a little in hindsight. The whole reason for booking that flight, and the ones like it before, was to save a bit of money against a trip that cost considerably more overall — the amount saved, weighed against the total cost of the trip, was close to nothing. Weighed against two or three days of feeling underslept, foggy, and slightly off, it’s a bad trade every time, and I kept making it anyway for years, because the money saved on the ticket was a cost I could see immediately, and the lost days a week later never quite got filed under the same mistake — the same blind spot that shows up in training, which is most of what recovery after 40 is actually about: the cost you can see is rarely the one that matters most.

What Actually Happens After a Bad Night

That’s really the whole lesson, and it has nothing to do with flights specifically. Some costs announce themselves the moment you pay them. Others show up a few days later, spread across sleep and mood and how much patience is left for your own kid at half past five in the morning, and because they arrive late and diffuse, they never get blamed on the decision that actually caused them. Sleep researchers have found that a single night of severe sleep restriction leaves a residual deficit even after a full night of recovery sleep — the fog doesn’t lift the moment you get one good night back, no matter how badly you want it to. One more reason a single lost night rarely stays contained to itself, and why trying to fix it with a catch-up nap or a long weekend lie-in only ever gets you partway there.

The fix, once I did the actual math, turned out simpler than the lesson took to learn. If a trip only works with a flight landing at midnight or leaving before six, I add a night now rather than force the calendar to absorb it. And I’ve stopped picking the destination first and accepting whatever flight times come attached to it — I let the schedule help decide where I’m going, not just how I’m getting there. The cheapest decision is rarely the one with the lowest total cost.

Frequently asked questions

Does one bad night of sleep really take multiple days to recover from?

Often, yes, especially after severe restriction rather than a normal short night. Research on sleep restriction has found that a single night of recovery sleep doesn’t fully resolve the deficit — some measures of alertness and performance stay impaired for several days afterward, even once you feel subjectively rested.

Why does an early or late flight disrupt sleep more than expected?

The flight time itself is rarely the real number. Getting to and from the airport, security, baggage, and ground transport typically add two to three hours on either end, which is the part most people forget to plan around when a flight “sounds” early or late enough to be manageable.

Is a nap the next day enough to make up for a very short night?

It helps with subjective sleepiness, but it doesn’t fully substitute for lost sleep. Studies on recovery sleep consistently show that alertness can bounce back faster than actual performance and mood, which is why you can feel “fine” the next day and still be operating at a deficit.

How can I avoid sleep disruption when booking cheap or budget flights?

Treat arrival and departure time as the true anchor, not the flight time on the ticket — add two to three hours on either side for a realistic estimate. If that pushes bedtime or wake time too far off schedule, adding a night to the trip is usually cheaper in total than the days lost to recovering afterward.
