As senior management from the world's airline industry gather in Doha, Qatar this week for the IATA Annual General Meeting (AGM), Aviation Week Managing Editor Jens Flottau, Brussels Bureau Chief Cathy Buyck and I kick around a few thoughts with Engagement Editor Rupa Haria on what the themes of this year's conference might be. Will Qatar's gleaming new Hammad International Airport be able to the region's phenomenal airline traffic growth? How will the fight over whether Gulf carriers are subsidized -- to not -- play out? And who benefits from open-skies agreements? Listen to the special edition of our Check Six podcast to hear what we think the industry will be talking about this week.
