People have mentioned the massive amount of major airline retirements at the end of the decade until the end of the following decade.
Also, consider the effects of consolidation. Fewer airlines and pricing power means fewer flights and seats are needed. Even the LCCs will likely raise fares considerably above what they are now due to the favorable economics of high demand for less seats. When will the majors finally begin to use the pricing power?
The majors dont need or really want large regionals anymore. If the pilot shortage gets bad enough, they can simply shrink and even essentially liquidate the regionals. If Republic gets too expensive, for example, mainline guys would be happy to take on the E170 flying. If Republic cant staff with the rates or if mainline has too many retirements, management can either take the planes to mainline with mainline rates or park the planes.
For dispatchers I think the short term is ok for everyone but in the long term 4-6 years from now I think it will be hard or impossible to take the regional route to the majors. Either a university degree or internal hires will likely get become the preferred route to the majors simply because regionals may not exist or will be so small only the senior lifers remain. Thats why I say the next four years are critical for those entering the business now who want to take the regional route to the majors.
I dont think management will want or be able to sustain regional flying at higher rates. With a pilot shortage of their own brewing, I would not be at all surprised to see the majors use it as an excuse to get out of regional contracts and also get rid of old planes of their own that they have been trying to park.
Consolidation means airlines dont need as many hub airports anymore. If anything, fewer hubs and more focus cities may be the future of a consolidated industry. The lack of competition makes it easier to have less flights and charge more money for it. The people that need to fly will still fly but with fewer flights and less seats they will need to pay more for it.
Remember, Airways couldnt get enough E190 captains to fill every captain spot available. Airways has an extremely senior group on the East side. Legacy AA has an average age in the mid fifties for the pilot group. The bottom starts to drop around 2018.
One thing to watch out for are the supplementals and LCCs. If the majors are forced to raise pay due to all the retirements and a high cost to learn to fly, those places may or may not be able to stop their own crews from taking higher pay and going to the majors. Southwest will be fine obviously but will Frontier, JetBlue, and Spirit be able to keep all their pilots and attract new hires for low pay rates if the majors need to raise their pay? Even the ease of getting hired at the majors could hurt the other carriers who wont be able to match the wages at the majors assuming no changes in pay rates occur. I doubt Spirit, Frontier and JetBlue can raise pilot pay much more and stay competitive with the Big Three. Even Southwest has the same problem but with their rates so high it will take a lot to not be able to attract new people. All that Southwest will struggle with is keeping their status as a LCC.
