Ive flown Taca/Lacsa numerous times , never flew LAN. If I had teh choice LAN wins hands down!

Taca uses the 320/319/321 all narrow bodies. Id rather fly on LAN that uses mainly wide-bodies from most US Cities. Could be a narrow body out of say MIA or any place by the border. I would imagine if they fly into the SF area its with wide-bodies only

Taca is a really a no-frills Carrier. They arent bad I flew mainly in Biz but its not real Biz. When I had the chance I jumped onto Avianca! But Id assume LAN should be be good also
