US joins ONEWORLD March 31st 2014
Officially announced today on the "NewAmerican" web page:
"On March 31, 2014, US Airways will join the oneworldŽ alliance...".
US will continue to operate separately through most of 2014 and FF programs won't be merged until late 2014 or possibly with the 2015 benefit year. However, some reciprocal benefits will start January 7th (lounge access, some elite benefits when flying on the other airline, posting miles to either program when flying US or AA).
