Over the last years Paypal has firmly established itself as a mainstream online payment provider with millions of users worldwide. An increasing number of international airlines allow Paypal to be used for flight ticket payments.
Be aware that some airlines can have various restrictions – a Paypal payment option may only be available for residents of certain countries. Sometimes only flights priced in specific currencies may be available for Paypal purchase.
When paying by Paypal do check the payment fee that the airline charges – compare this with other forms of payment that may be available. Using Paypal it is possible to make the payment via a credit card, debit card, bank transfer or using any positive balance in your account.
Finally, consider that paying by credit card directly (not via Paypal) in many countries will offer you a far higher degree of consumer protection should the airline go bankrupt. For example, in the UK paying by credit card for goods priced £100 to £30,000 makes the retailer and card company jointly liable.
