Just curious if there's anyway to check loads on non-US carriers? I'm traveling this week with a ton of options, but all different carriers, many of them foreign. myidtravel gives you the happy/unsure/sad faces, but that's it. Is there anywhere to get an actual seat availability list for a foreign carrier as a standby traveler?

Try PPRUNE

I use the StaffTraveler app.

There's a FB group called non-rev loads you can ask to join. Pretty good and quick on there

Definitely StaffTraveler app.

Stafftraveler is absolutely unbeatable. Usually I have loads in minutes.
