We suggest taking a look at KLM’s current “Break Away” fare promotion.
It offers decent roundtrip fares between Amsterdam and several European cities: Birmingham, Edinburgh, Geneva, Helsinki, London, Madrid, Manchester, Marseille, Milan, and Paris. The cheapest listed Break Away fare is Amsterdam-Paris, which begins at €147. Afraid of fare creep via undisclosed fees and taxes? Don’t be. These fares include all additional charges.
In most cases, Break Away promotional fares last through November.
