I didn't think that was legal but I forget about the cargo carveout and all my 121 experience has been post 117, so I'm not super familiar with it.
Story time, post 117 (July 2024):
I had three 14+ hour locals with min-rest overnights in base in a row, ~5am showtimes. Day four was another 5am show, with a deadhead SFO-ORD, three hours of RDY, then a 20 hour overnight with a ~18:00 local show that ended at midnight in OKC. I was excited to finally get some rest.
I got to sleep around 0400 chicago time (0200 base time) in preparation for my PM switch. Well, 04:30 my phone rang. I switched it to DND and flipped it over. CS kept calling until it rang through. (I have that set on since I'm perpetual AM reserve and don't want to miss a call for having it in the wrong mode)
NBD. I turned it to silent mode, rolled over and went back to sleep.
A few minutes later, the phone in my hotel room starts ringing. Groggy, I start digging around for a way to unplug it, but the I'm in one of the wedge rooms in the Hyatt Regency O'Hare, and the line is hard-wired to the phone, then goes behind a desk that's attached to the wall.
It keeps ringing. Annoyed, I finally answer it.
(Paraphrasing):
"Hi Captain, you have a 0630 show."
"No. I'm at rest, and rest must be prospective in nature."
"You had ten hours of rest, you're legal."
"I've only been asleep for half an hour. I didn't voluntarily answer the phone—you can't just war-dial my room. I'm at rest."
"It's legal."
"I want to speak to the crew time coordinator, right now."
"Ok, but she'll say the same thing."
TL;DR: She did. "You had 10 hours of rest, you're legal."
Asked to be forwarded to the MOD.
MOD, very salty: "Yeah, it's legal. You answered the phone."
"CS called me in my hotel room."
"You're in a hotel room <the company> PAYS FOR, of course we can call you." (Sarcastic, 'I hate pilots' voice, 'pays for' emphasized like I'm on vacation or something) "If you don't like it, unplug the phone next time.,"
"I can't unplug this phone. I've only had half an hour of sleep, and you interrupted my rest."
"(Something like "that sounds like a 'you' problem"). Are you saying you're fatigued?"
"Of course I'm fatigued."
My fatigue report was denied.
All the holes in 117 have been discovered and exploited at this point; 117 is a target, not a limit.
