Bomber Command was just
one RAF command - equivalent, if you like, to the 8th AF alone, except fighting from 1939 - 1945 without a break. Bomber Command had, I've read, the second highest loss rate of any force in the war - only the U Boat crews lost a higher percentage. Note sure of the stats behind it, but I can well believe it.
The British Commonwealth's other arms included Coastal, Fighter, Training and 2 Tactical Air Force in the UK; the Empire Training Scheme across the Commonwealth; air forces in the middle and far east, as well as north Africa and the Mediterranean - and then there's the other losses by the RCAF, RNZAF, RAAF, SAAF etc.
I've not found any total casualty figures as per your question with a brief look (good Q, BTW) but some things to think about:
I think these are all correct - they are hard to prove either way, of course.
The USA lost more people in the great influenza pandemic of 1919 than in all the wars fought in the 20th Century.
It's unlikely we will ever know the true casualty figures for the Eastern Front in both world wars.
It's been calculated that we killed more people in warfare in the 20th Century than in the entirety of human history to 1900. And the 21st C isn't looking too good so far.

All branches of service -Served: 11,115,000 Killed/Missing: 580,000 Wounded: 475,000 Prisoner: 318,000 Percent killed: 5.2%
They present the US forces broken down into arms, and have separated out the USAAF from the Army.
