Well this is a few months late, but I wanted to thank everyone for their help. The responses to this thread actually answered a question I was just about to ask about codeshares from KBP to LGW. (appears that is out of the question)
Thanks everybody :)

Do flights on Buddy Passes earn miles?
 

A friend uses these all time and never enters his Skymiles number. I'm thinking probably not, but thought I'd ask the experts.

Buddy passes as well as non rev travel DO NOT qualify for
skymiles credit.

Any thing related to employee travel benefits do not qualify for FF credit.

The last two posters are correct. You can enter your SM# (I think), but it will just show "NO FF CREDIT" on the BP.

On another note, before you commit to a buddy pass, make sure that you can't get a confirmed discount Y ticket for less or close. Sometimes buddy passes aren't really worth it.

J-M is absolutely right. Using a buddy pass can be a little bit like gambling in Vegas. Never bet what you cant afford to lose, or in this case dont use a buddy pass when you absolutely have to be somewhere. You might wish you had searched for that discount Y class ticket when you cant get back to work from HNL and your boss gets mad :D

They are an absolute waste domestically. I have a high amount of them to share with "Friends and Family" every year and I only let them use them if they are traveling off season to international destinations and don't mind being flexible. From a value perspective there are just very few places out to ATL in the US that make sense to even try.

A couple of years ago, a family of four was stuck in HNL for five days before giving up on their Buddy Passes. IIRC, they ended up buying four walk up Y tickets on Hawaiian.

The only thing below buddy passes on the NRSA priority list are other airlines ZED fares (and even those arent always below buddy passes).

Thats how my wife does it too from SLC. Ive seen buddy passes fly business class from JFK-BUD and back. I've also watch buddy passes get stranded in DUB for 3 days because of oversold flights.

Even off-season isnt great to NRSA travelers but its a better bet than high/normal season.

With employment dates of 58, 62, and 65 in my cadre, I'm pretty sure my folks will get on before most other BP riders. It's the employ crowd that we can't beat. I used to mess around with these things myself but rarely, rarely do anymore. Oddly, if I must fly ATL to BNA they come in pretty handy. That is one expensive ticket on Delta normally (but only $157 according to FareCompare right now) and has proven to be one effective use of them domestically.

Does DL give the employee's priority when the employee accompanies the buddy? CO does, and in my work group there were several cases of employees flying with a buddy just to be sure that the buddy received the higher priority, then turning around and flying home once the buddy had reached the destination (including a couple of TATL flights).

No. If you are family and are pass riders you can travel at the same priority as the employee, but that is it.

Retirees? What S class do you normally travel on?

One of those above is a retiree I still have bennies through. I'm an S3B when on DL and an S3CR on Connection flights.

My buddy pass experiences:

TLV-ATL in February: Biz was practically empty in both directions. I had no one sitting next to me.

TLV-ATL in October: The plane was jammed. I was very fortunate to be able to get an aisle seat in Y. It was the last row, the seat did not recline, but at least the remaining empty seat on the flight was the middle seat next to me.

ATL-TLV in November: My originally scheduled flight was full. I spent overnight in ATL and flew out the next day in Biz.

Season is the big factor with buddy passes. I wouldn't dream of attempting this during the high season.
