Whether I go on an airline's website or on a travel site like Expedia it seems to be the same story when checking on the availability of seats. Since I travel with my wife alone we like to get two seats that are separate from other seats. On the B777 and B747 aircraft the configuration is usually 3-4-3. However there are about 6 to 12 sets of seats that are only 2 each where the fuselage narrows near the back of the aircraft. No matter how many months in advance that one checks I have never seen these seats available to be chosen on line. I am wondering if I go to a local travel agency if they would have access to those seats. Or do the airlines just routinely block certain seats?
