overall very good; just found a bit poor the food options in Narita airport but the in the flight it was good but limited (no real choice to avoid seafood or clearly stay away from pork..); most of the food was tasty tho and the choice was nice, specially their snacks and dessert and drinks. The in-flight systems was so-so (too complicated interface; they should rehaul with a proper UIX), and I specially appreciated their segments of videos capsules about the behind the scenes including an overview of technicalities of their aircraft and days in the life of their pilots. It was refreshing and give a good ideas of the efforts and challenges every employees has to deal with. Loved it!

Guam airport overview

Guam International Airport, officially known as Antonio B. Won Pat International Airport, is situated on the central part of the north coast of Guam. Everything is close by in Guam and the airport is no exception: it’s a mere 5km (3 miles) east of Agana (Hagatna), the capital city of Guam.

Guam International Airport was originally used as a military airport during World War II. In 1992, the first passenger terminal at the airport began to operate as travellers started to realise that Guam had more to offer in terms of beaches, sun and sea. The terminal consists of three levels: arrivals go through the basement level of the terminal, the second floor is mostly admin and the departure gates are located on the third floor.

The airport has served as the perfect base in Micronesia for Continental Airlines. The Antonio B.
