The worst time to buy travel insurance is when you’re already at the airport, slightly panicked, staring at a kiosk that offers you three tiers of coverage with names like ‘Classic’, ‘Plus’, and ‘Elite’. That’s not a product designed for your benefit. It’s designed for impulse purchasing under time pressure.
Airport and airline-add-on policies are almost always overpriced relative to what they cover. The medical limits tend to be low, the exclusion lists long, and the emergency assistance networks thin. You’re paying a premium for the convenience of buying at the last minute — which is exactly when you have the least ability to compare anything.
Buy Before You Leave, Not the Night Before
The practical window for buying travel insurance is after you’ve booked your flights but more than 24 hours before departure. That gap matters because some policies — particularly those covering trip cancellation for ‘any reason’ — require purchase within a set number of days of your initial trip deposit. Miss that window and you’re locked out of the broader cancellation coverage regardless of what you pay.
Comparison sites like InsureMyTrip, Squaremouth (both US-focused), or Battleface for more flexible international cover let you filter by what actually matters: emergency medical limits, medical evacuation coverage, and whether pre-existing conditions are covered. Read the Product Disclosure Statement, not just the summary table.
The One Number That Actually Matters
Emergency medical evacuation. Not the overall policy limit — the evacuation sub-limit specifically. A medical evacuation from Southeast Asia or a remote part of South America can cost upwards of USD $50,000 to $100,000. If your policy caps evacuation at $20,000, the rest comes out of your pocket. Many budget policies sold at checkout or airport kiosks have evacuation limits that would barely cover a domestic transfer.
Aim for unlimited or at minimum USD $500,000 in medical evacuation cover if you’re travelling outside your home country’s public health system.
Credit Card Cover Is Usually Not Enough Alone
Some premium credit cards include travel insurance as a cardholder benefit, and it’s worth knowing what yours offers — but read the activation conditions carefully. Many require you to have charged the full fare to the card. Most have lower medical limits than standalone policies and patchy evacuation cover. It can work as a supplement, but treating it as your primary cover is a gamble most destinations don’t warrant taking.
The boring truth is that good travel insurance costs less than a single night in a mid-range hotel, and the only way to get it wrong is to not think about it until you’re already at the gate.
