This could be dangerous advice to anyone without military experience. The flows are taking up half of newhire classes, particularly at AA. That leaves only 50% of a class open to people off the street, most of which will be filled by pilots with a military background, secondary degree, family ties, gender or ethnic qualifiers, etc. I know the circumstances for Delta are slightly different because the flow doesn't take up quite as much of each class, but the result is mostly the same. Just my opinion, but the path to AA and Delta are much harder unless you work at a flow carrier or have extensive qualifications.
