Fam... I would be suprised to see 8-10 year upgrades at AAI. Besides, this industry has a way of flip flopping overnight. If fuel drops overnight or if DAL merges with someone, you can bet AAI will be there to pick up the slack. I don't believe AAI is going to downsize at all either. The 10% growth in 2008 was the highest growth rate of any airline. AAI is just getting in line with everyone else. AAI can also sell 737's for more than they paid for them, selling them would actually make a profit for AAI. My guess is that upgrade is going to head towards 5 or 6 years. But then again, this is the airlines. Tomorrow is another day, and if the US heads into a recession, who knows. It going to be a double edged sword for the airlines. Fuel demand is going to go down so fuel prices will go down, yet pax traffic will decline as well.. Too bad fuel prices won't drop while passenger demand increases... We can always dream.
