Drive4it

Hi,

I've a return flight from Hesthrow to Gran Canaria with Portugal TAP airlines. It's a stopover in Lisbon both ways

The final leg Lisbon to Heathrow has been cancelled 

They are offering me a voucher.

Am I due a full refund?

Thanks all

When I dealt with SWISS their Involuntary refund policy was very clear...

10.2 Involuntary refunds

10.2.1 If we cancel a flight, fail to operate a flight reasonably according to schedule, fail to land at your final or Stopover destination or cause you to miss an onward flight for which you hold a confirmed reservation, we will award you a refund.

 
10.2.2 If no Flight Coupons have been used, we will refund the fare paid, including all taxes, charges and fees.

10.2.3 If one or more Flight Coupons have been used, we will refund at least the difference between the fare paid and the applicable Tariff for travel between the points for which the Ticket has been used. We will also refund any taxes, charges or fees you have paid for those routes in your Ticket which you have not flown.
