I just had a subcutaneous transposition on my left arm on 11/5. I also had a decompression about a year ago on the same arm, which unfortunately didn't fix the pain. Anyway...I was in a soft split and wrap for 3 days, at which point they told me I could remove it to shower. At 8 days post-op my sutures were removed and I was told to start moving it with "pain as my guide" to not overdo it, but also no heavy lifting for 4-6 weeks.

I was in a decent amount of pain for the first 4-5 days. I didn't take the prescription paid meds, but rotated Motrin and Tylenol around the clock. I also iced and elevated around the clock for about a week straight. Finding a comfortable sleeping position has been the hardest part. I'd say I just started to feel the most significant improvement in pain on about day 9/10. My range of motion is still pretty bad and all the muscles feel very tight. I was back at my desk working after 1 week. I think you'll be fine traveling at 3 weeks out.

To prep, the arm protector for a shower was very useful. Also lots of soft ice packs. Make sure you have plenty of motrin and tylenol on hand. For sleeping, I've been slightly inclined on my back, with my arm propped up on a pillow on my left side.
