US Airways is in the process of launching a weekend only services between major cities and resort/holiday destinations. Last year, we saw Sat/Sun service from CLT to various caribbean and south american destinations, it is continuing with flights out of LGA and BOS to destinations like SJU and LAS.....today IAD to SJU service, Saturday only, was announced.
I find this approach a bit unusual, can US Airways make money with once a week services on these routes? Are these routes operated in connection with tour operators or cruise ship lines? Is this all about giving their Frequent Flyers more choice in using their miles?
