I got the email this morning and the site is finally up.... the email wasnt to ABC's usual standards it was simply text in a plain email but this is what it said-

- Ajira Airways
http://ajiraairways.com/ for the new website
I am currently investigating the site but here is what I have found interesting so far-
The promotional video-The video plays on the site homepage. An almost identical video was shown on the Dharma Special Access Week 6 promotional video. A single frame in the video shows a limo driver holding the sign "जॉत 316", which translates from Devanagari as "John 316" (see easter eggs section). There is also a date stamp on the bottom right corner of this frame of January 21, 2009, which is also the date of the broadcast premiere of Season 5.
The list of places they fly to and from-
The sample ticket-
The ticket is linked to Guam international airport
The Source code- A number of messages in hexadecimal coding have been found in the site source code on different pages. They are:
"For God so loved the world that he gave his one and only Son, that whoever believes in him shall not perish but have eternal life." (From the Bible, John 3:16 - links to the Ajira promotional video).
"So off they started about Irish sport and shoneen games the like of lawn tennis and about hurley and putting the stone and racy of the soil and building up a nation once again and all of that." (This is a quote from James Joyce's novel 'Ulysses', notably page 316).
Pineapples in Hawaii. (Pineapples in Hawaii are called Halakahiki).
Supersonic is commercial thirty till meridian.
"Where America's day begins." (The official motto of Guam).
Booking a flight-You could book a flight to Guam and get some images... It now says that all the seats are booked but here is how it did look-

As a result you got a ticket and some lost images-

and
Other info-When the Ajira Airways site launches, the plane flies across the screen, and an island is seen in the background. This island looks strikingly similar to the Island.
At the Lost signing event on November 19th 2008 at Meltdown Comics in Los Angeles, Ajira Beer was handed out to those in attendance, with the same logo as seen on the Ajira Airways website.
The website initially listed the names as E.H. MacCutcheon and Antonio B. McCutcheon, but this was quickly changed to E.M. MacCutcheon and Antonio B. MacCutcheon. (Possible link to Charles Widmore's Whisky?)
The site contains temperatures and times for major cities around the world. Rome, Italy is listed as 72 degrees at 8:28 - the sum of these numbers is 108, the sum of the Numbers from the show.
The five watermarks on the corners and top-center of the boarding pass are the same hieroglyphs found on the countdown timer in the Swan station.
Ajira Airways appears to be an Indian airline, as Devanagari (used in the logo and in the promotional video) is used to write many Indian-based languages.
Time in Los Angeles is marked as 11:30am on the site, and the time of flight 316 on the flight booking page is 11:30am.
The times listed with temperatures from around the world do not correspond. Each is several minutes faster or slower than the others from elsewhere in the world. While this would make sense for hours, it does not for minutes, unless one calculates and accounts for time differentials the way Daniel Faraday does.
Several cities share the same minutes - :x1 - Santa Monica, Ames; :x3 - Bangkok, Tustin, NYC; :x4 - Tokyo, Wellington; :x6 Seoul, Portland.
Many of the cities listed are connected to the main characters of the show. (example: Santa Monica-Hurley; Ames-Kate; Tustin - Locke).
Seven of the cities appear to be the birthplaces or residences of those who must return to the Island (i.e., the Oceanic 6 plus Ben and Locke) -- Jack (Los Angeles); Ben (Portland); Sun (Seoul); Sayid (Baghdad); Locke (Tustin); Kate (Ames); Hurley (Santa Monica).
Four other cities are the capital cities of Mexico (Mexico City), Italy (Rome), New Zealand (Wellington), and Thailand (Bangkok).
Prior to the site's relaunch on December 29th, ABC issued a number of LOST-themed postcards. Some of the postcards featured the Ajira logo-

The site news ticker says under news "South Pacific Triangle: Pilots and sailors avoid a new Pacific location trouble area". This suggests that part of the Pacific Ocean is becoming notorious similar to a Bermuda Triangle area, and this assertion might be linked to the Island (or more specifically the consequences of its disappearance).
One of the flashed images shows N824. Similarly N842M is the call sign from the helicopter in season 4
