I second the Briggs and Riley recommendation, contact them directly to discuss flight crew discounts. They offer a 20% discount but you need to contact them for a discount code.
Really if you ever flown 3 day trips that start late and finish with a transcon redeye. I’d say that’s a mediocre intro to Europe flying. You actually spend more time in the seat fly domestic. And to prepare for the leg back you will be actually sleeping when it’s dark outside.
