about 7 weeks (per my son just got one in early june)
my husband has a card and i have a card.
we signed up years ago and each got 60,000 miles providing we met the spending requirements.
They have a 50k bonus right now. Not sure we would have enough time to get them for a November trip by the time we meet the spending limits then add 7 weeks. Worth a try though for 2 free round trip (takes some work to get the right days/points)
What I do is pay some of my monthly bills.. just went to the bank and did my car/truck payment, hit the grocery stores, and other bills
Come home and pay southwest account right away. So I get the points right away and use them for air flights to Aruba only.
Already have enough points for me to go back.. working on the husband now.
