A detailed package outlining the rules under which Taiwanese airlines will be allowed to apply for the proposed charter flights to the mainland over Lunar New Year could be issued as early as today. The package of rules was originally due to be unveiled last week, but some airline sources said it had been held up by internal politicking within the Executive Yuan as some government factions wanted tighter controls. Sources said they now expected the package to be publicly unveiled by the end of this week. Mainland authorities have already sent the Taiwanese carriers instructions on how to apply for Lunar New Year charter flights via the Taipei Airlines Association, which was also used by Taiwan to negotiate the current air service deals with Hong Kong and Macau. A senior manager at EVA Airways, Taiwan's second largest airline, confirmed it had received the package from Beijing's General Administration for Civil Aviation, which he described as 'quite accommodating'. However, he said parts of the package would likely be rejected by Taipei, including a demand that mainland carriers be allowed to take part if there was another round of charter flights. 'As far as I know, the Executive Yuan is not ready to release the package yet, but my contacts at the Ministry of Transportation say that it is almost ready,' the EVA source said. However, the Taipei package was unlikely to include a response to the administration's instructions and would only deal with requirements for the Taiwanese carriers, he said. 'The government's package will set the rules for the charters, such as what type of passengers will be allowed to book seats; which ground-handling agent to use on the mainland and what airports to use to fly out of Taiwan,' he said. The Taiwanese government is also not expected to budge from its requirement that the charter flights make a technical stop in Hong Kong or Macau before proceeding to the mainland. Another senior source said the six main Taiwanese airlines had agreed to limit the Lunar New Year operations to two round-trip charter services each. The administration's instructions say the Taiwanese carriers will have to file applications 15 days ahead of the planned departure dates.
