Working for small regionals can often work out better for people with kids. The jobs not as high profile but the smaller network can afford you more certainty and balance in your job. To be honest, working small aircraft can be a real joy too. Being a mainline flight attendant is actually quite a demanding job as the airline requires a lot of flexibility from you, the workloads are higher and you'll be required to work anywhere on their network, which spans the entire country.
