The 12 Mistakes

Stop Making These Expensive Travel Mistakes

1

💸 Cost: $50–$300 per flight

Booking Flights Directly on the Airline Website

❌ The mistake: Going straight to an airline website and booking the first price you see — without comparing alternatives.

✅ The fix: Always use Aviasales first. It searches 100+ airlines and agencies simultaneously with zero markups — showing you the real lowest price. Takes 2 extra minutes and can save you $200+.

Airlines have zero incentive to show you a competitor's cheaper flight. A comparison tool like Aviasales does that work for you instantly — and the flexible date calendar shows you which days are cheapest for your route.

💸 Cost: $50–$200 per trip

Paying Roaming Charges Instead of Getting an eSIM

❌ The mistake: Turning on international roaming and getting a bill of $10–$15 per day — or buying an overpriced SIM card at the airport in a panic.

✅ The fix: Buy an Airalo eSIM before you travel. Plans start from just a few dollars for several GB of data. Install it at home — land anywhere — be connected instantly. No queues, no roaming shock.

For a 2-week trip, roaming charges can add up to $140–$210. An Airalo eSIM for the same trip costs around $8–$15. The math is embarrassingly simple — yet millions of travelers still pay roaming fees every year.

💸 Cost: $40–$200 per rental

Renting a Car at the Airport Counter

❌ The mistake: Walking up to an airport car rental counter without a prior booking and paying whatever price is shown — which is almost always 40–60% higher than online rates.

✅ The fix: Always book your rental car in advance online through GetRentaCar. Compare dozens of suppliers in 150+ countries in one place. Book 4+ weeks ahead for maximum savings.

Airport rental counters know you're tired, you need a car immediately, and you have no alternative. They price accordingly. Pre-booking online removes all that leverage from them — and puts the savings back in your pocket.

💸 Cost: $1,000–$50,000

Traveling Without Travel Insurance

❌ The mistake: Skipping travel insurance to save money — then getting sick abroad, having a flight cancelled, or losing luggage with no coverage whatsoever.

✅ The fix: Get EKTA Travel Insurance from just $0.99 per day. Medical emergencies, trip cancellation, lost luggage, and COVID-19 — all covered. Buy online in 3 minutes right after you book your flights.

A hospital visit in the USA costs $5,000–$10,000 without insurance. Even in cheaper destinations, an emergency evacuation can cost $15,000–$50,000. EKTA insurance for a 2-week trip costs less than $15. This is the most expensive mistake on this entire list.

5

💸 Cost: Up to €600 lost

Not Claiming Flight Compensation You're Owed

❌ The mistake: Having a flight cancelled or delayed by 3+ hours — accepting a voucher or nothing at all — and walking away without knowing you were legally owed up to €600 in cash compensation.

✅ The fix: Use AirHelp to check any cancelled or delayed flight — even from up to 3 years ago. They handle everything for free. No win means absolutely no fee.

Airlines count on passengers not knowing their rights. Less than 3% of eligible passengers ever claim compensation. AirHelp exists specifically to fix this — with legal experts who take on airlines on your behalf.

6

💸 Cost: $20–$80 per trip

Using Your Regular Bank Card Abroad

❌ The mistake: Using your regular bank card for purchases and ATM withdrawals abroad — paying 1.5–3% foreign transaction fees plus ATM fees on every single transaction.

✅ The fix: Use a travel-friendly card like Revolut or Wise that offers zero foreign transaction fees and free ATM withdrawals up to a monthly limit. Set one up before your trip — it's free and takes 10 minutes.

On a $1,500 trip spending budget, a 2% foreign transaction fee costs you $30 — silently, invisibly, on every purchase. Add ATM fees and that number climbs higher. A travel card eliminates all of this instantly.

7

💸 Cost: $30–$120 per trip

Paying for Checked Luggage You Don't Need

❌ The mistake: Packing too much and paying $30–$60 per bag each way on budget airlines — spending $120+ in baggage fees that could have been completely avoided.

✅ The fix: Master carry-on only travel. Roll your clothes, use compression bags, wear your heaviest items on the plane. Most trips of up to 2 weeks can be done with a carry-on if you pack smart.

Budget airlines make enormous profits from baggage fees precisely because travelers habitually overpack. A capsule wardrobe of 5–7 versatile pieces covers every situation — and leaves money in your pocket instead of theirs.

8

💸 Cost: $10–$40 per day

Eating Only in Tourist Area Restaurants

❌ The mistake: Eating every meal at restaurants in the main tourist square — paying 2–3x more than local prices for food that's often mediocre and inauthentic.

✅ The fix: Walk 5–10 minutes away from the main tourist area and eat where locals eat. Look for restaurants with menus in the local language, packed at lunchtime, with no photos on the menu. Use Google Maps to find highly-rated local spots.

On a 10-day trip spending $30 per day on tourist restaurant food versus $10 on local food — that's $200 saved. Enough to cover your entire Airalo eSIM, travel insurance, and a day tour. And the local food is almost always better.

9

💸 Cost: $50–$200

Booking Travel Too Late

❌ The mistake: Leaving trip planning to the last minute — booking flights 2–3 weeks before departure when prices have already surged, and finding accommodation fully booked.

✅ The fix: Set a price alert on Aviasales 8 weeks before your intended travel date. Book flights 4–6 weeks in advance for domestic trips and 2–4 months ahead for international. Book accommodation as soon as flights are confirmed.

Last-minute flight prices can be 40–80% higher than advance booking prices for the same seat on the same flight. The earlier you plan — the more money stays in your budget for experiences that actually matter.

10

💸 Cost: $20–$80

Choosing "Pay in Your Home Currency" Abroad

❌ The mistake: When a card terminal or ATM abroad asks "Pay in USD/EUR or local currency?" — choosing your home currency because it feels safer and more familiar.

✅ The fix: ALWAYS choose the local currency. The "pay in your home currency" option — called Dynamic Currency Conversion — adds a 3–7% markup on the exchange rate that goes directly to the merchant's bank. Always choose local currency and let your own bank convert it.

This is one of the most invisible and widespread travel scams — and it's completely legal. The terminal makes it look like you're being helpful to yourself. You're not. Always refuse and choose local currency every time.

11

💸 Cost: $30–$150

Booking Accommodation in the Tourist Center

❌ The mistake: Booking the most conveniently located hotel right in the heart of the tourist area — paying a massive location premium for the privilege of being surrounded by other tourists.

✅ The fix: Book accommodation 1–2 kilometers outside the tourist center and use local transport or walking to reach attractions. Prices drop 30–60% just a short distance from the main square — and the neighborhood experience is often far more authentic.

Being "in the center" sounds appealing but often means noise, crowds, expensive restaurants on every corner, and tourist-trap shops. A 10-minute metro ride gives you a real neighborhood experience and keeps significantly more money in your pocket.

12

💸 Cost: $50–$300

Traveling in Peak Season Without Flexibility

❌ The mistake: Insisting on traveling during the most popular weeks of the year — school holidays, Christmas, Easter, summer peak — and paying maximum prices for flights, accommodation, and activities.

✅ The fix: Travel in the shoulder season — just before or after peak season. You get 80–90% of the same weather and experience for 40–60% lower prices. Use the Aviasales flexible date calendar to instantly see the cheapest weeks to travel to your destination.

Shoulder season is one of the best-kept secrets in travel. May and September in Europe. April and October in Southeast Asia. November in the Caribbean. Same beautiful destinations — dramatically lower prices and far fewer crowds.
