Dafuq you need ATIS for if you're already on the ILS?
Seriously, all the shit dudes have said here rings true. The only thing I'll add is that one's success in making the transition if you choose that path in the future isn't a given. It takes some work and a simple but crucial understanding that you're entering a completely different environment. Harder? Hell no, not by a country mile. Apply yourself maybe half as much as you did to get through UPT and you'll be fine. But thinking that being a SH Viper, Hornet, Raptor, -17, whatever guy is going to carry you through on its own is a mistake. Your mil status is also not a guaranteed job offer. The airlines don't start beating your door down when they find out you're available though, at the current hiring rate it may seem like that for some guys. Expect to put in some time prepping for interviews and realize you're breaking very new ground. There's lots of gouge from the bros out their and several well run companies that'll relieve you of a small, but worthwhile investment to make sure you're ready to sell yourself when the time comes. It's a multi-million dollar career that many mil guys have missed out on because they decided to wing it and figured WIC, a 1000 hours of IP time in the Viper or some other feather in their cap was going to make it a breeze.
Not hard.....just different......way different.
Oh and while I gocha here......The shit some mil guys do and say (the famous 5% we've all met) when they finally start their new careers would make you cringe. The tools who have come before you leave a lasting legacy. When you hear the stereotypes assigned to us all thanks to those clowns, you'll maybe have a slightly understanding of what it's been like being an Eagle driver since that fateful day at Kadena 30+ years ago .
So, try to play nice with the civilians. Taking every opportunity to attempt to impress them with combat stories or "there I was" BS, making them feel inferior in general or lecturing them on how things were back in your old life isn't generally the best option. There will be plenty of bros in the other seat to swap stories with but not always. Also, accepting that airline X is paying your a shit-ton of money to fly their jet the way they want you to and not how you think it should be flown is also extremely helpful. Adjust accordingly and be one of the 95%. Good luck with whatever path you choose.
