Argus analyst John Staszak upgraded Southwest Airlines to Buy from Hold with a $73 price target, citing the recent improvements in domestic airline fares along with the positive outlook for stronger revenue per seat mile, or RASM, in the coming quarters. The analyst also notes Southwest's operational upgrades, with expected revenue contribution from the "sale of boarding slots, improvements in the frequent-flier program, a new reservation system, and a new credit card agreement with Chase." Staszak raises his FY19 EPS view to $5.15 from $5.10 and also expects the airline's Q3 RASM to come in at the top of the management's prior guidance of -1% to +1%.
