After increasing the international checked baggage allowance, Japan Airlines will increase its domestic flights' baggage allowance. From August 1 2011, JAL will implement the following changes on its domestic flights

15kg -> 20kg
max 3 piece -> unlimited
max 45kg -> max 32kg per piece and max combined 45kg or 100kg
no change in dimension limit
Excess baggage charge varies -> excess baggage charge 300 JPY per kg except for some short flight.

For more details, you can refer to JAL website. You can find the excess baggage charge table here.

Before this, JAL has been serving Champagne Piper Heidsieck in Business Class and Premium Economy Class. But now, JAL has updated its offering as follow:

Long Haul First Class (except Los Angeles): Champagne Salon S 1999 and Champagne Joseph Perrier Cuvee Josephine 2002
Los Angles and Jakarta First Class: Champagne Cuvée Louise Pommery Blanc 1999 and Champagne Drappier Grande Sendrée 2002
Long/Medium Haul Business Class: Champagne Delamotte Brut
Short Haul Business Class: Champagne Piper Heidsieck or Champagne Pommery Brut Royal
Premium Economy Class: Champagne Pommery Brut Royal

I don't really know much about champagne as I don't really drink them except when I fly :P So is this supposed to be an enhancement over Piper Heidsieck or this is just a cost saving measure?

Japan Airlines has made some enhancement/changes to its inflight meals recently. One of them is a new collaboration dish with Mos Burger served in Premium Economy and Economy class called "Air Mos Burger". This is only available on flights departing from Japan to New York, Chicago, Los Angeles, Frankfurt and London. Looks like this will be a full meal not just snack (because Y doesn't really serve snack like this :p)

For more info, you can visit JAL website (Premium Economy/Economy). Sorry it's in Japanese only.

[Update 3: JAL has yet made another slight modification to the seat map. For the latest version of the seat map, please refer to this post]
[Update 2: JAL has updated the 787 seat map. The seat maps shown on this page is outdated. For the slightly outdated version of the seat map, please refer to this post]
[Update: Added link to JAL NRT-BOS route page]

Japan Airlines (JAL) loaded the seat map of its 787 used on the new NRT-BOS route tonight. It has 2-2-2 configuration in Business Class cabin, and a 2-3-2 configuration in Economy Class cabin. This is just like the 763 cabin! It has a total of 237 seats (30C 207Y). In fact, if you look closer, it has the exact same configuration (minus the galley and lavatory) as the 767-300ER's A41 configuration. Below is the seat map taken from JAL website. (Please note that this is from the booking engine, not from the JAL aircraft configuration page. Therefore it could just be a placeholder until the final seat map is out as some have pointed out 7 seats per row in Y is a bit generous)

From today's NRT-BOS press release

In addition to its relationship with American, JAL has also begun discussions to strengthen its U.S. network structure with JetBlue Airways, utilizing the carrier’s hub operations in Boston to provide customers more options and smoother connections to and from major destinations in the East Coast.

Since JAL doesn't codeshare with JetBlue at the moment, this could just mean codesharing. But mileage earning on them would be nice too...but too bad this won't give your FOPs...so I guess I still have to stick with AA on domestic travel :(
