Yet again SATA has cancelled its London / Manchester to Ponta Delgada flights with little notice and making no effort to assist passengers who have had to either cancel their plans completely or alternatively book expensive last minute flights between London via Lisbon which means they fully benefit from the ticket between Lisbon and Ponta Delgada. I have complained about the situation to Customer Services (they don't know the meaning of the word) and the European Commission as have my friends and no one as usual receives a reply from the airline. Please be aware that this company has a complete monopoly on certain routes in and out of these islands (sometimes with a TAP codeshare) and you are at their mercy. They do not respond to complaints properly (or at all in many cases) particularly if something is serious. Open competition will come to these routes soon and maybe then this airline will have to treat its customers with respect. If you do actually fly with them on a flight you will find service standards to be good.
