OK boys, time for a reality check.
American is NOT a better partner than Delta for El Al. American has virtually NO domestic feed at JFK. They don't even fly to their hub in Chicago from Kennedy. I challenge you to look at their JFK schedule. They provide virtually NO connections for EL Al to feed.
Here the 18 North American cities that AA serves from JFK (AA and Eagle, but mostly Eagle): ALB,BUF,CLT,CMH,DCA,DFW,LAX,PHL,PIT,PVD,RDU,ROC,SAN,SEA,SFO,SJC,SYR,YUL
Compare that to then 28 North American cites served byt he DL code (mostly mainline Delta). Be sure to look at the size of the cities compared to AA's:
There is no justification for the idea that AA is a better partner for El Al. Do you think that perhaps El Al has a vague idea of what kind of partner that American is??? They have been partner's for years. They would not be switching to Delta unless they KNEW it was a better option.
Also, oneworld in NOT stronger than SkyTeam. It isn't even a real alliance. The two largerst carrier's cannot even codeshare! oneworld will continue to disinigrate as AA moves closer to the Qualiflyer airlines and BA makes it's merger move. SkyTeam may be new, but it already has a strong base with key hubs in strong locations. It will continue to attract member and will eventually challenge Star. It may never have the number of airlines that Star has, but it will have strong positions in the world's largest markets. (North America, TransAtlantic...eventually the Intra-Asian market)
To sum...Delta is a far better partner for any carrier flying into JFK than American. It only takes a quick look at a schedule to see it. Don't assume that because it's name is "American" Airlines, it is the best airline partner.
