I thought the way the pricing was done was just wrong. You charged 60 pounds for baggage up front and I could have managed with 8 kilos. It made me choose the cheaper flight and then get the baggage charge in the process of filling out the form when it was already too late to waste my time and go and find another company. Finnair told me I could put my baggage on the plane at no charge. Too late then. I thought it was a trick. and a foolish trick on your part that will cost you .

Left late from Heathrow. On arrival at Helsinki we only had 10 mins to clear customs and meet our connection. We had to run through the airport with our 3 children and all our luggage only just making the flight not a great start to our holiday with only 50 mins between flights there is no room for any error

If only the flights had taken off on time. Only one of the 4 flights did which makes connections and onwards travel unnecessarily stressful. Otherwise I can't fault them.
