Kaohsiung's mayoral campaign has entered its final 100 days, with both main candidates staking out their pitches — good news for voters who want the city's airport expanded, since it is now a central campaign promise.

• Democratic Progressive Party candidate Lai Jui-lung toured Kaohsiung airport with lawmakers and transport officials, pushing a three-stage upgrade plan.
• The plan covers finishing the new Siaogang terminal, adding more international routes and bigger planes, and eventually building a 24-hour offshore international airport.
• He also called for a crackdown on illegal taxi touts and better queuing and waiting areas under the airport's new pre-booked taxi scheme.
• Kuomintang candidate Ko Chih-en framed the countdown as a last sprint to "win Kaohsiung back," pointing to four years of staying in the city after her defeat last time.
• A new multi-storey car park on the airport's east side opens next year, with lawmakers urging sweeteners for nearby residents.

Outlook: Expect both camps to keep leaning on transport and infrastructure promises as the vote approaches, with the airport the clearest dividing line so far.
