TAP is back in the news today, for seemingly good and definitely bad reasons. The ‘seemingly good’ is the reinstallation of the Lisbon-Porto route, and the fact that the airline plans to run 1,200 flights per week in the summer. For some, this will be the chance to rush backwards and forwards between the two cities much faster. Others have already remarked it is a terrible decision in terms of climate effect, as there are perfectly good trains to use, and the journey is relativey short. So, what is the definitely bad reason? It is that trips will all cost (even) more than usual due to the increased price of jet fuel which has forced the company to put up its ‘fuel tax’.
