hey goldilocks,
i am flying spirit also in oct.
you can secure your seat assignments 90 days before the day you leave.
i sat up last night and confirmed mine at 12:01 as the 4th it is 90 days out for me.
you can then print your boarding passes 45 days out and up to 12 hours before your flight leaves.
when you do the seat assignments on line, only 60% of the seats will be available. the rows from 1-7 and the last three rows and exit rows are seat confirmed at the counter at the airport. if you do not want to sit in the seats that are available 90 days out, then go to the spirit counter and request those seats then on the day you leave.
they hold those seats for handicap and some for families with small children.
i was going togo for the bulk head seat as i need the leg room but went ahead and booked row 8 this morning.
about luggage, you are allowed 2 bags up to 70 lbs. , one carry on besides a purse/laptop/briefcase,etc.
any more ??, just ask.
i may have forgotten some of your questions, i get typing and forget the other points lol
