Per this FyerTalk thread, there seems to be a pretty good fare war going on between oneworld and SkyTeam for travel between the west coast and Europe.
SkyTeam seems to be publishing good business class fares to oneworld hubs, while oneworld seems to be publishing good fares to SkyTeam hubs.
For example, oneworld airlines have ~$2,000 business class fares between Los Angeles and Rome, which is a great fare to begin with. This seems to be valid for travel on American, British Airways, Iberia, and US Airways.
However, it gets much better than that. I recently wrote about how AARP members can receive $400 off business class tickets booked through British Airways (anyone can join, and it costs just $16). The best thing is that this is valid on codeshare flights as well, so you can take advantage of this fare for travel on most oneworld carriers operating transatlantic flights as long as you book through the AARP link.
That potentially brings down the cost to a roundtrip business class ticket between Los Angeles and Rome to ~$1,600.
Keep in mind that British Airways actually lets you use Avios to upgrade to first class at a very reasonable cost, though there does need to be award space in order to be able to upgrade.
These business class fares seem to be valid through next summer, so that’s potentially an amazing deal for business class summertime travel. However, the $400 discount for booking tickets through British Airways is only valid for outbound travel through March 31, 2015.
This is available to and from quite a few markets, though I’m on a plane right now and can’t easily search all of them. I do also see the fare available from Seattle. I’m sure it’s available from other cities in the US, and also to other cities in Europe. I figured it was better posting about it now, as I’m sure this fare won’t last.
Hopefully some of you can take advantage of this! I’m certainly tempted, as a way to requalify for status and collect miles with either American or Alaska.
