Flying with Gastroenteritis (Stomach Flu): What You Need to Know Before Travelling
Gastroenteritis — often called the “stomach flu” — is a common condition caused by a viral or bacterial infection that inflames the stomach and intestines. It typically results in diarrhoea, vomiting, stomach cramps, and sometimes fever and fatigue. Though usually short-lived, it can be highly unpleasant — and highly contagious.
If you’ve caught gastroenteritis and are due to travel, especially by air, you may be wondering whether it’s safe or even allowed. Here’s what you need to know before boarding that flight — and how DrNote.co.uk can help.
🤢 Is It Safe to Fly with Gastroenteritis?
Generally, no. Flying while actively ill with vomiting or diarrhoea is not only uncomfortable for you, but also poses a risk to fellow passengers. Additionally, air travel can worsen dehydration and fatigue — common symptoms of Gastroenteritis (“stomach flu”) — and aircraft toilets aren’t ideal when you’re unwell.
Key Points to Consider
1. Contagious Period
Gastroenteritis is often contagious from the moment symptoms begin until at least 48 hours after symptoms have stopped. It’s commonly spread through:
Contaminated food or water
Direct contact with an infected person
Surfaces touched after vomiting or using the toilet
Flying during the contagious phase can lead to outbreaks, especially in closed environments like planes or airports.
2. Airline Policies
Most airlines discourage travel when passengers have vomiting or diarrhoea within 24–48 hours of the flight. Cabin crew may refuse boarding if you appear visibly unwell. If you’re recovering, some airlines may ask for a medical certificate stating you’re fit to travel.
3. Health Risks on a Plane
Flying while ill with gastroenteritis increases the risk of:
Severe dehydration
Spreading the infection to other passengers
Exhaustion due to low energy levels
Inability to access toilets in time, especially during take-off or turbulence
4. Travel Insurance
If you’re forced to cancel or postpone your travel due to illness, travel insurance that covers medical issues can help with flight rebooking or refunds. A doctor’s note or sick certificate from a qualified provider like DrNote can support your claim.
