SW online check-in?

[shelly3girls]

We are leaving in 3 days traveling on SW to MCO out of PHL. I have never flown SW so I am unsure of the exact policies. I heard that SW would soon be allowing online check-in even with multiple people under the same reservation number. Is this possible yet or do I need to get new confirm numbers? Also, does SW still preboard children under 5 even though there will probably be many families on this flight. I will be traveling without DH but with my DDs 3 and 5. There is no chance my girls would fly without sitting next to me. Of course if no one would move for me they are more than welcome to babysit/ entertain/ be tortured by my DD3.

Bad news-If they've change the policy it hasn't hit their website yet:

Determine if you are eligible.
Online Checkin/Print Boarding Pass is available beginning at 12:01 AM local time on the day of departure and ends one hour prior to departure.
If any of the following items apply, your reservation does not qualify for Online Checkin:

More than one person is traveling under your confirmation number.
You have a group, senior, youth, infant, military, or other passenger-specific fare type.
You have a paper ticket.
Your flight has already departed.

Good news-you can preboard:

Prior to general boarding, Customers with disabilities, unaccompanied children, and families with children under five years of age will preboard. Customers holding boarding pass "A" will begin general boarding, followed by Customers with boarding pass "B," and then "C."
