Moderator note.
The OP invited members of FlyerTalk to make recommendations as to brokers in the private jet charter field. Since then, some brokers or operators have joined apparently for the sole or primary purpose of promoting their commercial business. This practice runs afoul of a basic Rule of service of FlyerTalk (Rule 10) which bars commercial posts, except for very limited instances not applicable here. (All Rules are available for view under the Help menu near the top of each site page.) Going forward, let's honor the non-commercial terms of FlyerTalk's discussion forums and avoid commercial business touting their respective enterprises. Thanks, Ocn Vw 1K, Senior Moderator.
