If I could give Finnair less than one star I absolutely would. I booked a flight with them for travel to and from Helsinki, and on my return flight home, things went terribly wrong. After being delayed out of Helsinki by an hour and half, I missed my connecting flight at Heathrow. In a 560,000 square foot facility, I could not find a single representative to help me rebook my travel nor could I get through to someone when I called their customer service.
I ended up paying $2,000 to book a United flight to get home and $400 for a hotel room for the night.
Upon returning to the US, I have tried repeatedly to get Finnair to take responsibility for what happened and instead of apologizing, they informed that I had plenty of time to make my connection (I physically could not get through security at the new terminal) and if I had "wanted" to change my itinerary, I could have done so on their website.
What I WANTED was to be on my flight that I originally booked. What I WANTED was to get back to DC for important matters that I had going on the next day. What I WANTED was for someone at Finnair to help me and resolve the situation. But instead, they implied that I was lying about what happened, and I "voluntarily" missed my flight.
As someone in the customer service industry, I can not image ever treating someone the way I have been treated.
