Passengers flying in economy no longer need to suffer in silence and endure an uncomfortable lack of legroom.
While economy is the answer for those after cheap flights, often if you want extra legroom you'll need to pay for the privilege, with extra fees for selecting seats (especially the comfiest ones).
Luckily, you won't need to fork out on a First Class ticket for a bit of extra comfort, as there are some easy tricks to bagging the best seats at no extra cost.
