US airline shares were down across the board yesterday – with the exception of Alaska Airlines, +0.4% – as the broader market pulled back after a strong recent run of gains on fresh European sovereign debt concerns.

Allegiant slumped 4.1% as oil prices rose, defying falls in most commodities.

US Airways dropped 3.7%, while Delta Air Lines fell 3.3%. In an investors presentation, Delta confirmed it will raise capacity by 1-3% next year.
