hello porker,
i flew to las vegas with maxjet earlier this year, and have booked again for next feb. i found the product excellent value for money, we paid £595 return all in this year and £650 for next.
the whole package is not as good as BA club world or virgin upper, but its a fraction of the price. its about equivilent to BA club about 7-8 years ago. there is fasttrack through security at stansted, and a good lounge. our flights were on time both ways, food and drink were very good, and loads of room with 60 inch seat pitch. the 767s are old, but perfectly acceptable.
the only downsides are that maxjet is a small carrier and so will not have much back up if an aircraft has a technical problem, but few of the top airlines have much back up nowdays.
its a far better product that BA WT+ or virgin premium economy for a similar price.
cheers
