JetBlue is at it again, with another one-day sale. This sale is hot on the heels of yesterday's version courtesy of Virgin America, and it is full of great deals, so if you've got the inclination and a few extra bucks, get a seat while they're hot.

What's next for airline in-flight entertainment? iPod hook ups! With the entry of in-flight WiFi, airlines seem to finally be "getting" it in terms of technology, and have decided to upgrade from the terrible days of having to watch the one in-flight film showing on the tiny screens that flip down from the ceilings. Virgin America and JetBlue have long been ahead of the curve, providing live televised programming in the back of every seat, and in Virgin's case, outlets at every seat. Now, though, the innovators over at Rockwell Collins have created a system that would allow passengers to hook up their iPods (and other personal media devices) to an individual seat's entertainment system.

JetBlue is unloading seats at some great prices -- but only today. Flights range from $29-$99 each way, but there are serious rules and regulations to these deals. First of all, the obvious -- you've got to hit "purchase" by 11:59 tonight. Second, sale fares to/from destinations in Florida are valid for travel between October 6 and December 16, 2009, on Mondays, Tuesdays, and Wednesdays for southbound travel, and Tuesdays, Wednesdays, and Thursdays for northbound travel. For everywhere else, destinations are valid for travel between October 6 and December 16, 2009, only on Tuesdays and Wednesdays.

JetBlue has gone and done something pretty sweet for the Faust family in the Washington area. And the best part about it, is that they did it with little fanfare. It seems that their 14 month old baby boy was accidentally burned scalding water and suffered serious burns on 65% of his little body. This kind of damage needed treatment from a 440-mile away Boston hospital. The family was about to purchase one of the $599 all-you-can-jet passes for the month of September/October so they could get back and forth to the treatment center, but JetBlue went ahead and stepped it up with some real human kindness. Read on, in the family's own words:

JetBlue has launched a neat program for the month of September, and they're calling it "All You Can Jet." Just like the "all you can eat" surf and turf joints in Las Vegas, the idea is that you can fill up your frequent flier account as much as you want during the month of unlimited travel, specifically September 8th to October 8th. The timing is definitely strategic, as they're offering this great deal just after Labor Day, so not many people should actually be able to fly every week, but those that can, should.

JetBlue has launched a great contest for all the foodies out there. Basically they're going to pay for your dinner, but it's a whole lot sexier than that since they're teaming up with Restaurant Week in New York and sending you out for a night on the town.

For so long now, JetBlue has hovered around the periphery of Los Angeles, dropping passengers some 75 minutes south at the Long Beach "John Wayne" airport, and some 45 minutes northeast at the Burbank "Bob Hope" airport. While they expanded to cover San Diego and San Francisco (SFO mind you, not OAK), LAX wasn't part of the JetBlue equation -- at least, until yesterday. The first time I took a JetBlue flight it was out of the tiny Burbank airport. With its four gates and outdoor luggage carousel, the Burbank airport always feels like you're already on vacation because of the relative lack of chaos. To me, that was always part of the charm of JetBlue -- the tiny airport (and the DirectTV). However, I'm happy to report that JetBlue has finally cracked the inner circle and is now serving LAX direct from JFK, connecting two giant hubs with leather seats and free wifi. I was on the inaugural flight from JFK's fancy pants terminal 5 to LAX's bizzaro cul-de-sac terminal (has anyone else been to the 67B gates with the mini escalators?), and I have to say, it was pretty fun.

Watch out Jet Blue, Southwest, and Virgin America -- upstart Jet America is after your customers. Jet America is following in the footsteps of airlines like EasyJet and Ryanair, offering ridiculously low prices on flights, then nickel and diming the hell out of you. Each flight will offer nine $9 one-way seats, and as of now, the airline flies between Lansing, New York (Newark), Detroit, Toledo, Minneapolis, South Bend, and Orlando. Fees start ticking as soon as you choose flights. There's already a $5 "convenience fee" to book online, which is better than the $20 fee to book on the phone, so either way you slice it, your $9 ticket will jump to $14, if not $29.

JetBlue is digging around for marketing ploys to boost sagging traffic. They've already launched a huge sale, with deals as low as $109 each way between Los Angeles and New York. Now they've decided to throw a bone to all those in danger of getting canned. Until June 1, if you happen to lose your job between now and your date of departure, JetBlue's typical no-refund stance is bendable. All you have to do is notify the airline two weeks prior to your departure date that you're "between engagements" professionally, and they'll refund you the ticket.

JetBlue and Virgin America continue to circle each other and are now squaring off to battle over Los Angeles (LAX), Long Beach, Boston, and New York (JFK). JetBlue announced this morning that they will be offering daily non-stop flights from to Boston and JFK from LAX starting late this spring. Virgin America is beating JetBlue to the punch and will be offering the same nonstop routes starting next month. Tickets are currently hovering around $300 round trip. Virgin America is also trying to steal airspace from JetBlue and Southwest with a new route from the SNA airport (Long Beach) to San Francisco (SFO), $59 each way. JetBlue currently flies from the close-by LGB (Long Beach) airport to SFO as well.
