Did you pay by credit card? If so then no need to worry.
Also, I got an email from MaxJet, they say don't worry too

Dear Friend of MAXjet:
Recently, you may have heard—incorrectly—that MAXjet is cancelling flights due to financial issues. Please be assured that we have not cancelled and are not cancelling any MAXjet flights. MAXjet is stronger than ever, with 34 non-stop flights per week between London and the US (New York, Las Vegas and Los Angeles).
We have completed 100% of our scheduled flights and have an on-time performance record of 82% for November and December to date. This is a fantastic record for an international airline. I am confident we will continue to improve on this as we head into 2008.
We take great pride in knowing that we have created a great Business Class product at an incredible value. Customers have responded to our product and the new category we invented. And we continue to receive many awards for our all-business-class product from such prestigious publications as Travel + Leisure and Zagat’s.
In addition, we are continuing to expand our service. We have much in store for you, our customers, in 2008 and I am excited to share the news with you shortly.
If you have any questions or concerns, please do not hesitate to contact us. My team is most happy to answer your questions. Contact us at 1-888-I-FLY-MAX or email us at
info@maxjet.com. For more information, please click here for the full press release

Sincerely yours,

CEO and President
