There has been talk of a pilot shortage for a long time now. That being said the retirement numbers are staggering beginning in the next 2-3 years and continuing for about the following decade. There is also the new FAA rest requirements that will take place in the next year and a half which will require increased staffing almost everywhere.
These facts being said, you still have to consider other external factors (oil prices, state of the economy, etc).
No one can really tell you if in 1-2 years the golden gates will be opening for the airlines. In my opinion in that time frame (towards the end more than likely) every airline in the US will be hiring like mad.
