Also, keep in mind there’s not a big pay gap between 7erb vs 73nb. Now 330b vs 73nb....now you’re looking at a bigger gap - assuming you don’t pick up GSs.
My guess, you still have 5-10 years to fly 7er category if you want

I went from 50% on a NB (not the 737) to 80% on the ER. I'd never done international and wanted to try it and I also wanted an out if I didn't like it. As it turned out I loved being international but hated getting there. I couldn't sleep on my break when in the back of my mind I knew I had to go back to work in 2-3 hours. I slept a grand total of 0 minutes over the course of 8 ocean crossings and decided to bid back to the left seat of a NB.

That said, while I was on the ER my schedule at 80% (and eventually 70%) was better than it had ever been at 50% on my previous plane. The layovers were usually in nicer places and of longer duration. I bid to fly with LCAs and over the course of a year about 70% of my trips were awarded with LCAs. After the inevitable swap the pot, sick outs, and lack of OE I probably got bought off 1-2 times a month. I was also able to hide during the winter on reserve and I didn't fly a whole lot. I never WS'd and always had a GS in, I was probably awarded a GS every other month or so.

Your base matters. I think most of the ER bases are staying the same or growing while ATL is getting smaller. Joining a growing category is almost always a good thing. Good luck with your decision.

Thanks!!!!

IMO when in doubt, and it seems like you are, don't try and fix what ain't broke. You can always do it later when your seniority is better. Next couple of years will produce amazing movement and you still have plenty of time (better part of a decade at least) to try international in general and the ER in particular.

Hans experience is pretty common for those who don't stay int'l. Sleep is the big adjustment.

This is a huge determinant of happiness on either fleet. Many pilots struggle with this and leave the intl fleets for exactly that reason. The nice thing about the 7ER vs 330 is you have a domestic option to keep your body within 2 hours of where it lives. If you can sleep on command, the intl trips are great. If you can't sleep anywhere but a soft comfy bed at your normal bed time, you will be miserable.

Anyone know if you lose currency, can you still do CQ or do you have to go do recency training first?

It is, definitely. I never slept on break unless I was dog-tired and it was reasonably smooth, but flying to Europe for a two or 3 day layover was a great balance for that. On the other hand, 24 hour Paris layovers with 6:30 pickups and 2 hour van rides were no bueno. Coming home from Asia was always a death march. Some guys sleep great, for them, flying to Joburg or Sydney is like getting paid to sleep. If you're new to international, expect the first few trips to be rough, until you get used to the fatigue and know what to expect from your body. Then it's more just learning what works for you.

When flying internationally, caffeine can be your best friend or your worst enemy.

S2B... Only 1 pass rider or can my entire family use them? The wording on Deltanet seems to indicate the former.
