I'd like to share my experience on Silverjet, for anyone out there who's keen to fly/try business class transatlantic but doesn't want to have to pay the extortionate fares they charge on airlines like British Airways. Right now they only have one flight a day, but I was told they'll be flying twice a week by the summer and three times a week by the end of the year. They also plan to fly to more destinations, including someone said Dubai.
I think they're on to a good thing if they can make it work (which they must be). The plane is designed to carry 300 people but there are just 100 seats, so there's a lot more room. I think that was the best thing about the experience on board, the feeling of not being a sardine: on some flights I get claustrophobia. This was the opposite.
The whole aircraft is business class. I found it very luxurious, and I've flown several airlines in business class before. The food was good (you can order special meals in advance if you want, though I just had the standard choice, which I enjoyed). The seats are comfy: they're 6' 3" long, on a slight angle, but they lie flat, unlike the usual seats. There was also a massage function which was nice. You also get given your own individual entertainment system, so you can watch whatever you want when you want.
Silverjet also has its very own separate terminal at Luton with a 'Silver Lounge', and there's also a lounge at the other end, Newark. You can use the lounges and get breakfast and even have a shower on departure and on arrival, which is a great idea. They had a proper breakfast and for those who like to indulge that early in the morning there was champagne too.
You have to get to Luton/Newark just 30 minutes before your flight (though I didn't dare leave it that late), which is great compared to the usual 2 hours. There wasn't even a queue for check-in, probably because there are much fewer seats to fill, and they're only flying the one route. If you're checking in for a BA flight, for example, you have to line up with everyone going on every flight around that time. This made a big difference at security too, which is my personal horror: there was none of this cattle thing you get at Heathrow. I think I got through in about 5 minutes all told, straight out of the lounge.
If money's no object to you, then maybe you might still want to fly First Class, but for a fraction of the price I thought Silverjet was pretty amazing. It's going to be tough flying economy again, that's for sure!
