Been there...done that
The preverbial question of the ages. Trust me...it's a tough one. Having done exactly what you are asking about I'll give my opinion. I flew for a commuter for about 1.5 years and had the most fun I've had at a flying job. Didn't get paid worth a crap, but the schedule was perfect (no overnights, all day trips), the guys I flew with were awesome, and upgrade was quick. It was more of a party than a job.
Then they closed my domicile which just happened to be home for me. So I was going to have to commute, get a crashpad and a "beater" airport car...all on poverty wages. So I went to one of the local corporate operators, stumbled into a job and they gave me an offer I couldn't refuse. HUGE dollars, 2 jet type ratings, and all right out home. No brainer right? Well, not having any corp. experience I did what most anyone would do. I took the job with the expectation of finishing my career there.
Now I'm left seat flying jets all over the country. Staying at the best hotels, spending $200 for dinner every night, and basically not believing it because I was used to eating pb&j up at cruise because we didn't even hardly get dinner breaks at the commuter. We'd fly to one destination in particular about 90% of the time so that started to get old. And we'd fly for 2 hours and sit for 2 days. Now flying the best equipment out there was great, but we spent most of our time sitting and not much flying...about 300-350 hours a year in the seat. I started to feel like less and less of a pilot and more like a "business planner" and eventually I realized that I wanted to be flying more. Even the plush hotels got old after you spend so much time in them.
So, I made a call and got on at another regional in the area. I took a $40,000 pay cut to do it, but for me it was what I had to do to enjoy my job. There was just no fun in the corp. gig compared to the laid back atmosphere at the airlines. I worked at that regional for 6 months and then my "first choice" hometown airline finally gave me an interview and I got hired. There is no doubt that the bizjet time helped me so I'm glad I did it...plus now I know what corp. flying is all about. What can I say...I had to know.
After 3 months on line at the airline of my dreams, Sept. 11th happened and I've been furloughed since Nov. 1st. Things are looking up for us and I anticipate being back by the end of the year if nothing else comes up, I'm just glad I'm not furloughed from United or some other major....I feel bad for those guys, most of whom may never get back. So, my advice to you is...if you have a good job flying corporate, right now isn't the best to be thinking about a job at a major airline. Nationals or regionals might have some opportunities for you but you will take a big pay cut going to a regional. I'd wait for a national before I'd take an airline job. If I knew what was coming I wouldn't have left the corp. job, I wouldn't have enjoyed it as much, but there were those occasional Alaskan fishing trips. The airlines will pick up and will be hiring again...not the majors, but there are a lot of good nationals as well as regionals out there.
That's my story...sorry for the length. I hope it is of some value to you and your decision. All and all I don't regret any of the moves I've made, they've given me some great experience. They also allow me to say when somebody asks this type of question..."been there...done that."
