Flying into CAN in January. Is there any preference out there for which flight to take through NRT. Looks like SEA has an A332, DTW has a 744 that allows for only an hour connection, and MSP has two 744 options, one with an hour connection and the other with closer to two hour connections. Most of my travel has been domestic and I've never been through NRT, so I don't know how much time I need to allow. Also, any recos on seats in business class on the various flights to NRT and from NRT-CAN. Also, looks like I'll have about a day to kill before my business starts in CAN. Any favorite things to do while in CAN? Thanks in advance.
