Less Than a Shoestring asked me to compare Porter and Air Berlin. What an interesting request! The airlines are quite different in terms of model yet both stand above their competitors in terms of the on-board experience they offer.
Porter operates almost exclusively along a point-to-point model, with almost all routes running either to or from Toronto City Centre airport. The point-to-point approach, interestingly, is more associated with low-cost carriers than it is with traditional carriers. Porter is not a low-cost airline, however, but rather a business airline with a fare structure that enables budget travelers to book flights relatively cheaply. A regional airline, Porter operates Bombardier Q400 turboprops that can only fly short-haul distances. Porter has a beautiful, compelling, carefully conceptualized brand.
Air Berlin, by way of contrast, bills itself as a low-cost carrier yet departs significantly from the low-cost carrier model. It sells connecting flights and provides snacks, drinks, and newspapers free of charge on board. Other departures from the low-cost carrier model include assigned seating and a frequent flyer program. The airline flies to around 80 destinations in Europe and beyond out of one major base and several big hubs in Germany and Spain. Its brand went through a major rework last year, though the livery associated with the rebranding has not yet been imposed universally. Air Berlin also operates codeshare agreements with several other airlines, a decision that further weakens brand stability.
Most importantly for budget travelers, both airlines offer inexpensive advance fares, and both provide an experience in the skies well above average.
