I understand now. Makes no sense to the casual traveller who doesn't read into such details. I though a partner is a partner is a partner!

I still don't understand why the 2nd leg of the flight was credited then? So should I look into getting the mileage credit on the 1st leg thru another airline?

Flying a flight marked by one airline (flight number), operated by a second airline and crediting the miles to a third airlines ffp is always problematic. Usually only works if all 3 are in the same alliance (Oneworld - Star - Skyteam) or specific provision. e.g AA miles on QF marketed flight operated by EK.

You live and learn my friend. Many moons ago I took a summer trip to Vietnam with friends - convinced them to all sign up for AAdvantage accounts (I already had one) since we'd all earn a bunch of miles, right? I neglected to realize that while on AA metal (at least to NRT, then NRT-SGN on JL), our flights were all booked as VN codeshares, so zero AA miles for us. Of course, this is back when AA and VN codeshared (prior to VN joining Skyteam). The big "Vietnam Airlines" paper ticket should've tipped me off - guess not!

Haven't made that mistake since.

The second leg was also operated by Etihad, marketed by Jet? If so, then I'm not sure what's going on. Could've been an error, or could be something else.

Regardless, it's definitely not the case that "a partner is a partner ...", even within the Oneworld alliance! It's entirely possible to have a flight ticketed by one airline, marketed by another, and operated by a third, and what mileage is credited (if any) can come down to the details of this. So it's always worth studying the fine print in advance (and asking folks on FT if things seem ambiguous)

Partnerships have written agreements. The agreements have terms and conditions negotiated between the partners before they signed the agreements. If you don't pay attention to those, chances are the outcome won't be what you expect.

Rereading this thread I'm guessing that the 2nd flight was marketed by and operated by Jet - Manish can you confirm this? Did both flights have a 9W code? I'm guessing IAD-AUH was 9W coded and EY operated (even if it was Jetihad - I'm too lazy to look up if EY operates Jetihad aircraft to IAD). Am also guessing that AUH-DEL was 9W coded and operated.

You could also try to see if you can get some JetPrivilege or Etihad Guest miles for the first flight? If you go to India often enough they could come in handy. Either EY or 9W could deny your request though because they could easily see that you earned AA miles for AUH-DEL.

The second flight was almost certainly 9W marketed and operated and therefore eligible for accrual.

Yes, definitely a complicated situation and I expect most casual travelers would get tripped up on this.

Instead of thinking that a partner is a partner is a partner, remind yourself that a partner of a partner is not necessarily a partner especially if they're not all full members of the same alliance.

Lesson learned.

Regarding the denied flight, can I pursue the mileage credit on Etihad since I have an Etihad account already?

I don't currently have a Jet Airways mileage account.

Don't see why not, nothing is stopping you

Additionally:

Jet marketed and operated flights with fares in B, H, K, V, O, G, W earn no miles; in N, L, Q, S earn 50%; only Y, M, T, U in economy (or F, A, C, J, I, P, Z) earn 100%. Only Award (redeemable) miles, not Elite Qualifying at that.

But yes, it appears you flew a codeshare - a Jet marketed flight operated by Etihad, which like an Iberia flight operated by SN, earns no miles.

Always check AA miles earning pages before buying if you intend to earn Elite Qualifying or Award miles; start here, and read carefully (read the wikipost at the top of the page).

I have another (absolutely crazy) data point to add to this whole 500-mile premium fare debacle...

I flew: DTW-DFW-LAS-PHX-DTW, all booked in P (a 2x EQM earning class).

LAS-PHX is 255 miles. I was credited with 510 miles. I called AAdvantage Customer Service to ask about getting my other 490 EQM. Original rep tried to tell me it was correct. He said he spoke to his supervisor, and the supervisor said it was correct. Asked to be transferred to supervisor after explaining to him that paid first class shouldn't net me only 10 EQM extra.

Supervisor got on the line, said the original rep misunderstood what she was saying and that the multiplier SHOULD in fact come after the minimum mileage, then told me I was "all set" and set to earn 750 EQM. I asked why, and she said "P earns 1.5x, not 2x." I directed her to the appropriate page, and she said "My mistake" and started typing again.

By the time the whole thing was over, I'd lost all my EQM credit for the entire set of flights, and she ended up having to re-credit them. My guess is they have a dropdown on their side that only allows them to choose "First," "Business," or "Coach." She said "Hmm, now it's multiplying everything by 3, but I'm just going to leave it because you had to call and sit on the phone for so long."

So, for DTW-DFW-LAS-PHX-DTW in P, I thought I was going to earn 8,426 EQM. Instead I earned 11,904 ^

The funny thing is, she still didn't credit the LAS-PHX flight correctly, as I earned 765 EQM (255 * 3).

She indicated that there was a publication on AA's side saying this multiplier multiplication issue was a known "System Glitch" and that a "Fix would be pushed later this month to correct it." So I may end up earning the extra 735 miles someday.

My spreadsheet is shot. There's an extra 369 RDM that just magically appeared that I can't account for as well.

That's what I'm told as well-- fix on the way, system not operating as intended at present.

Further confirmation of above from inside AA. He got a message from AAdvantage

So, they will do an adjustment for those that were shorted so far and the system will soon be fixed for real.

Cheers.

Excellent. I'll wait for the adjustment in the coming weeks. I'm flying this weekend on a paid premium fare SJC-LAX, so I'll see how the mileage credits. ^
