In December, the Japanese low-cost carrier Zipair started flying to San Jose Mineta from Tokyo Narita; now, it's doubling down on its commitment to the Bay Area by planning to launch San Francisco International service as well. A brief announcement from SFO this week provided no details on flight frequencies, fares or a specific starting date, saying only that the service would begin sometime this summer. Zipair is a wholly owned subsidiary of Japan Airlines that operates as a separate brand concentrating on the price-sensitive market. Its 290-passenger 787s include premium lie-flat seats with a 42-inch pitch and standard seating with a 31-inch pitch. Zipair also flies from Tokyo Narita to Los Angeles and Honolulu. Simple Flying observed that Zipair will face plenty of competition on its new route this summer, with United, Japan Airlines and All Nippon Airways each flying from SFO to both Tokyo Narita and Tokyo Haneda airports.
