I wrote a roundup on Skybus last month when they started selling tickets starting at just $10.
Here is a neat article about them:
“The Greyhound Bus of the Skies”
Also regarding Kosher food and their policy of not allowing food on flight:
“Thank you for contacting Skybus.
In general, you may bring your own food onboard a Skybus flight if we don’t offer a suitable alternative for sale. For example, the following types of food are not offered by Skybus and may therefore be brought with you:
-Baby formula and other types of baby food
-Special food for diabetics
-Special food for those with severe food allergies
-Special food for those with dietary restrictions (Kosher, Muslim, etc.)”
Finally, now that Skybus has started service, does anyone still doubt that “a la carte” airline pricing is inevitable?
