Ask Captain Lim ~ All about Aviation - Why are the seat configurations on the Boeing 777 in economy class is 2-5-2?

I frequently fly on United Airlines Boeing 777's and I have often wondered why the seat layout in economy class is 2 on the sides and 5 in the middle. Wouldn't it make more sense, and be more comfortable for the passengers in the middle rows, to have 3 sets of 3? Great job on the web site.

Hi Chris,

I am not so clear as to the rationale why the Airlines did not favor the three sets of 3 seats in the economy class. I suppose the reasons may be safety, convenience or uniformity. Remember the emergency exits are on either sides. With 2 seats, the obstruction problem may be considerably reduced. Convenience of service from either side may be another. Anyway, these are my opinion.

Check it out with the United Airlines or Boeing, they may be able to give you a better answer. Maybe your suggestion may earn you something the next time you travel with them!!
