Yes I would, and have booked Silverjet for two flights in the next month, at regular fares. Maxjet discounted like crazy before their demise.
Why? They consistently deliver on their promises.
Why? Because the number of available seats is refreshingly low on the online seat map, suggesting full flights (or clever marketing – I believe it is the former).
Why? Because my company supplies Silverjet, and they pay on time, every time.
I have faith in them!
