Whether you’re heading on holiday, travelling for work or just counting down a weekend away, it’s amazing how many period questions suddenly pop into your head once you’re sitting at the airport.
So, instead of pretending we’ve never Googled “can airport scanners see my Mooncup?” five minutes before boarding, we did the research and now we’re answering the top questions people google about their periods and flying.
Can airport scanners see a menstrual cup?
No need to worry.
Airport body scanners aren’t looking for menstrual cups, they’re looking for objects hidden under clothing. A menstrual cup can stay exactly where it is while you go through security.
There’s no requirement to remove your menstrual cup before going through airport security as it isn’t considered a prohibited item.
Can flying affect my period?
There’s no strong evidence that the altitude on a commercial flight changes your menstrual cycle or makes your period heavier.
What can make your period feel different is everything that comes with flying.
- Early starts
- Time zones
- Less sleep
- Stress
- Dehydration
- Hours spent sitting still
Together, those things can make symptoms like bloating, headaches, fatigue and cramps feel more noticeable, even though the flight itself isn’t changing your hormones.
Staying hydrated, moving around during longer flights where possible and getting as much rest as you can may help take the edge off.
Can flying affect my whole menstrual cycle?
It can, but again probably not for the reason you think.
It’s probably not the altitude, cabin pressure or plane itself. It’s the 4am alarm, the airport sprint and the fact you’ve slept for approximately 17 minutes. Basically, everything that comes along with travelling.
Jet lag can temporarily disrupt your body clock
Your menstrual cycle is influenced by hormones (hypothalamic-pituitary-ovarian (HPO) axis) that follow your body’s natural daily rhythm. Crossing time zones can temporarily throw that rhythm off, which may affect when you ovulate and, in turn, when your next period arrives.
Sleep plays a bigger role role than you might think
An early alarm, an overnight flight or trying to sleep sitting bolt upright can all disrupt your usual sleep pattern. Poor sleep can influence hormones like oestrogen and progesterone, which help regulate your menstrual cycle.
Travel stress affects hormones too
From racing through the airport to navigating a new country, travelling can increase cortisol, your body’s main stress hormone. Higher cortisol levels can sometimes interfere with the hormonal signals involved in ovulation, meaning your cycle might be a little earlier or later than usual.
The good news? It’s usually temporary
If you notice your cycle is slightly different after travelling, it’s usually nothing to worry about. Once you’re back to your normal routine, sleeping well and feeling less stressed, your hormones typically settle too.
Can I wash my Mooncup in an airplane bathroom?
Yes, but there’s a small caveat.
You can absolutely empty your Mooncup into the toilet during your flight. But we’d skip rinsing it with water from the airplane sink, as it’s not drinking-quality water.
Instead, take a bottle of water with you, empty your cup and give it a quick rinse. The Mooncup Cleaning Pot is made for moments like this. Just add clean bottled water, give it a shake, and your Mooncup is ready to go.
Top tip: if you’re emptying your Mooncup on a plane, aim for the middle of the toilet rather than the bowl. Airplane toilets use much less water than the one at home, so emptying into the middle means it’ll flush away much easier.
Can I delay my period for a holiday?
Sometimes, sure.
If your period is due to arrive halfway through your beach holiday or the day of a 12 hour flight, you’re not the first person to wonder if it can be postponed.
Depending on your circumstances, there are medical options that may allow you to delay your period. If you’re taking the combined contraceptive pill, you may already have options available to you. If you’re not, there are prescription medicines that can help delay a period in some cases.
They’re not suitable for everyone, so it’s worth speaking to your pharmacist well before you travel if it’s something you’re considering. They’ll be able to talk you through what’s safe and appropriate for you. NHS GPS are no longer advised to prescribe period delay medication for events such as holidays, patients are required to seek private assistance.
One thing to remember: delaying your period isn’t something you should feel you have to do. Plenty of people travel happily while on their period. If delaying it feels right for you, that’s a conversation worth having. If not, planning ahead with period care you trust can make travelling just as manageable.
Will flying affect my menstrual cup?
Not at all.
Changes in cabin pressure don’t affect how your menstrual cup works. It won’t suddenly lose its seal, overflow or behave differently just because you’re 35,000 feet in the air. There isn't any evidence to suggest that the cabin pressure on a commercial flight affects how a menstrual cup performs.
You can wear your Mooncup exactly as you would on any other day.
The only thing to think about is timing. If you're travelling for longer than usual, the same advice applies as always: empty and clean your cup every 12 hours (or sooner if your flow requires it).
If you think you'll need to empty your Mooncup during your journey, it's worth planning ahead. A bottle of drinking water or our Mooncup Cleaning Pot can make things much easier when you're away from your usual bathroom.
Can I take period products in my hand luggage?
Absolutely.
Pads, tampons, liners and your trusty Mooncup can all go in your hand luggage.
In fact, we think it’s always worth keeping some period care with you rather than packing everything in your checked suitcase. Because while airlines sometimes misplace luggage your period has never been known for waiting patiently.
So… should your period stop you travelling?
Absolutely not.
Travelling has a habit of throwing your routine out of the window. Early alarms, delayed flights, different time zones and questionable airport meal choices can all make your body feel a little different for a few days.
But the good news is that your period doesn’t need a separate passport.
A little planning, the right period care and knowing what to expect can make all the difference, whether you’re heading off for a weekend city break or the trip you’ve been counting down to all year.
Because the only thing you should have to be worrying about at the airport is whether your gate has changed.
Not your period.
