Ok, I should have taken the 50,000 mile offer three months ago ( https://creditcards.chase.com/a1/southwest/offer ). But now I want to travel in three and half more months, and those miles would sure be handy for a family of four. Are there any options for gaining Southwest miles bonus more quickly than waiting three billing cycles? I do see a signup bonus at Southwest checkout: * $100 statement credit, 10,000 miles for $500 spend in 3 months, plus (they don't highlight) $99 annual fee. Thus it's really a $1 credit plus 10,000 miles. The 50,000 mile bonus sounds better of course.
