If your flight is delayed, it is your responsibility to contact the rental company and inform them of the delay. You can find the company's contact details on the Voucher. If you are unable to contact the car supplier, you can contact our Customer Service team and we will do our best to inform you. Please note that if you do not arrive on time or if you do not inform the company of the delay, your reservation will be automatically canceled and will be considered as a no-show. Please refer to the Rental Conditions to see the grace period for your rental (the "grace period" means the additional time you are allowed in case of delay). If your flight is cancelled, the first thing to do is to contact our Customer Service team. We ask that you inform us of the flight cancellation before the agreed pick-up time, so that we can try to explain your situation to the supplier and ask you to keep the vehicle at your disposal so that you can collect it the next day. However, please note that in this case you will still have to pay for the first day as the vehicle has been reserved for you. We can also try to find another vehicle for you. In this case, the new price is usually a little higher than the original price due to the short term. However, we will send you a new Confirmation Voucher without charging another prepayment. If your flight is delayed or cancelled, we advise that you contact the airline for information about the refund procedure in the country in which you are traveling. Please note that flight delays and cancellations are beyond our control, therefore Oporto Car Rental is not responsible for any problems or additional costs incurred due to airlines.
