I'm pondering a trip to the Galapagos Islands later this year with my family and am wondering what my odds of snagging an EUA from IAH are into either UIO or GYE (we can fly into either locale). Are they like many other Latin/South American flights on CO -- full in coach but mostly empty in FC -- or am I going to encounter something more like the situation into EZE, where BF is routinely packed? (I realize CO flies 737s and standard FC into Ecuador) Will a trip during a holiday week lessen or improve my odds? (wasn't sure if most travelers there are business as opposed to leisure)
