SFO-LHR-LIS OW Biz/First $1755-1850/$2600
 

Good deals seems only ending in LIS, I checked a number of other cities in place of LIS but so far nothing-may be others. Also Finnair from SFO almost the same. First on BA also available about $900 more, I've actually got three on hold that I may not go through with so about $2600 will probably open back up.

Picked up a similar deal out of ORD a couple of weeks ago - ORD-LHR-LIS for $1400 O/W in UA Polaris J and TP.

Is this one-way or oneworld? One way fare doesn't seem so good.

Not sure what it went down to for the West Coast, but BA had the East Coast to Portugal in F for ~$1000 one-way after the AARP discount in November. $1755 in business or $2655 in first would be a good round-trip price in F, but as these appear to be one-way prices, I don't think this would be a steal.

Looks like both in this case lol

Also found SFO to LIS. Through Toronto, Air Canada/TAP
 

considered this also, all biz, unfortunately no Signature lounge not going all the way on Air Canada.

one way on BA or Finnair metal, latter obviously through HEL

This isn't a good price for a one-way

~$2K best I could find on TAP (non-stop)

not seeing anything on OneWorld carriers that comes close to this

This fare is everywhere. Just check forfares from multiple cities to Europe on Google flights you’ll see these low prices.

Yeah $2k roundtrip is pretty standard at the moment.
