Well in my research I am focusing on three types of Strategy: Low Cost, Differentiation and Niche

I have looked at the Failure of Laker Airways, due to losing sight of their strategy, which was originally Low Cost but tried to go more luxury.

I have Looked at Jet and Crude Oil prices and their affect on the industry and Ryanair's Cost Cutting Strategies.

I have looked at the affect of Natural Disasters (2010 Volcanic Ash Cloud) and Terror attacks

I have also researched M&A's (continental & United, IAG & BMI)
