Bound's hubby here:
Commercial airliners typically fly in controlled airspace. This would be between 20,000 feet MSL (Mean Sea Level) and 48,000 ft. MSL. The actual altitude will be assigned by air traffic control. Generally, they will fly as high as they can above 25,000 ft. for fuel economy/efficiency.
The exception to above, is on the airliner's are either taking off or landing.

It depends on the route but is generally between 30 to 50 thousand feet.
A point of interest; Concorde used to cruise at around 75 to 77 thousand feet or 14.5 miles. At that altitude the sky would look very dark and the horizon would look very curved.
The reason for the sky looking dark is another matter entirely.

Typically 10,000m to 11,000m or about 32,000 to 36,000ft. They may come lower for traffic reasons, or sometimes to pick up extra power and make up for lost time.
Inside the cabin, they pressurise it so you can live! But the pressure is not sea level; it is equivalent to about 2,500m or 8,000ft. That would be quite high for physical activity if you're not used to it, but OK for mainly sitting still.
Pressuring to 2,500m means the structure has to withstand a pressure difference of about 45 kiloPascals, half an Atmosphere
roughly. If they pressurised to sea level the difference would be 75kPa, requiring much greater stength, and thus weight.

10,000 feet for a smaller plane like maybe a Cessna 310 that doesn't have an O2 system but for like 727, 737, DC10 and some of those roughly 30,000ft. Just depends on air traffic and destination.

I seem to remember Pilots announcing various heights between 35,000 and 50,000 feet depending on their flight path. Does that sound about right? I'm sure someone will say if is isn't!!

Anthing from 20000 to 40000 feet but Concorde I think used to get to 70000 feet. The higher the better for fuel economy.
But why do they put frosted glass in the toilet windows ? That high who's going to look in ?

Depends, I flew to Belfast on Tuesday at 24,000 feet, however, with a bigger aircraft and longer distance you will typically be flying at around 30,000-35,000

Between 30,000 and 35,000 feet.

I think it's about 35,000 feet.
