Virtually the only game in OAK for regional flights. Check-in can be difficult, even if you pay for the three day Early Check-in. I've paid for it twice now and my $24 ($12.50 each way), has been rewarded with boarding passes A48 and A40. At the least, if you are in the A group, you can rest assured you will have bin space for your carryon. I'm not a big guy, but the seats are small. I pity those that are tall and/or a bit thick. The coffee and peanuts (oh no, peanut dust) are convenient. Rarely do I check luggage, but 2 for free is still a bargain. SWA is just like riding the bus. Cheap and it will get you there.
