Why Was My Credit Card Declined?

In nearly all cases, the decline comes from your card issuer (bank or provider), not BookingDuo. We use secure, standard payment gateways.

Common reasons & quick fixes

1. Credit/debit limit reached
   Ticket total (incl. taxes/fees) exceeds available credit or daily limit.
   Fix: Check your balance/limits in your banking app. Pay down if needed, then retry.
2. Bank security flag (very common for travel)
   High-value, international, or "unusual" purchases like flights often trigger auto-holds.
   Fix: Look for a verification text/email/app push from your bank — approve it right away. No alert? Call the number on your card's back to confirm the charge. They usually clear it instantly.
3. Location or IP mismatch
   Booking from Europe (e.g., Belgium) for non-local flights, or using VPN, can look suspicious.
   Fix: Pre-notify your bank about travel purchases, or try without VPN.
4. Entry errors
   Wrong card number, expiry, CVV, name, or billing address (must match bank's records exactly).
   Fix: Double-check all card details.
5. Card restrictions
   Prepaid, virtual, some debit/business cards, or issuer blocks on international/online travel. Please note that for security reasons, some cards/bank are not accepted by us.
   Fix: Pay via bank transfer (see below).
6. Temporary issues
   Glitch, expired card, or account hold.
   Fix: Wait 5–10 min, clear cache/incognito mode, retry. Check card status with issuer.

If your bank says everything's fine but it still fails, you can pay via bank transfer.
