Have you rued travelling in the low cost carriers or the cramped up economy sections of the full service carriers? Whether acceptable or not, it has been a fact of life that if you want to save on money while flying, you will have to live with the lesser space of your seats. But, this is fast changing as the carriers are realizing the need for diversifying their seat-portfolios on offer and are not just providing the cabin class experiences but are also providing more options for seating within a class of cabin, particularly the economy section.
International airlines have started offering more legroom seats to passengers which comes with an additional charge, which can be very steep at times. Lufthansa, KLM, Singapore, Etihad, United Airways and other such carriers have different charges for different location seats with more legroom. These seats could be the preferred ones, the exit row seats, the economy plus seats- all having more legroom space.
Whether you would be willing to pay the extra charges, which could be even three times the normal or standard fare would depend on a number of factors such as whether you are travelling alone or with family, desired level of comfort and, of course, the ability to pay more for economy in lieu of moving to a higher cabin class.
If you are traveling in economy sections of international carriers, it is worthwhile making a check on availability of these seats.
