2. Decreased capacity and routes
For the last two years, the airlines have steadily been grounding hundreds of planes, reducing their fleets by around 8 percent.
And this year carriers such as Frontier Airlines, American Airlines and Delta all announced they would continue the trend by either further cutting capacity or keeping capacity static. Not only does grounding flights get fuel-guzzling aircrafts out of the air, but it also helps keep demand high despite rising airfare costs. Plus, the airlines are pulling flights from low-yield routes or routes that don't make a lot of money per seat. That means fewer choices and higher prices on many nonbusiness travel routes.
