MIA and ATL
are pretty out of the way for a connection to SFO
- you're flying to the southeastern part of the US - much less direct than going through the middle of the country. So they're out. That leaves you with AA
, and UA
As far as service goes, I've read positives and negatives about all three carriers, although there was a recent trip report about a less-than-subpar experience with AA
. Even so, I would say that service is a non-issue. It really depends on the crew that you get.
If you want PTV's, CO
's 762 would have them as well as UA
's 763. AA
's 763 does not. CO
's 762 has one more inch of pitch than the UA
763 (32 vs. 31), but it's really not that big of a deal either.
However, the tiebreaker comes with regards to connections - ORD
in February is just too risky with the winter weather. Snow can wreak havoc on ORD
operations and connections, and it's simply not an issue for DFW
. If you were going during the summer, I wouldn't care, but for now, don't give yourself the undue stress.
As far as the DFW
segment goes, the CO
738 would have IFE and would be newer than the AA MD
-80, which has no IFE. Also, while food would probably be similar on the EZE
flights, you would have to pay on AA
and not on CO
In this case, CO
seems to be the winner, but compare the price difference between the two. If it's more than $50-75, go with AA
, but a slightly higher price for CO
might be worth it.
