With Spirit at LAX you check in at Terminal 2, go thru security in terminal 1, then you have to take a bus to the gate. When you return, you have to take the bus back to terminal 1 to get your luggage.

Be aware that you pay extra for even a carry-on suitcase, but you can bring a personal item at no extra charge (purse, computer bag, etc). There is typically turbulence going into and out of Las Vegas during the warm season.

Super short flight, so don't expect a full beverage service. Bring something on board after you get through TSA.
