Just completed my first Jetsgo flight yesterday. As posted above, online booking was dead easy, fare was $104.00 from YYZ-YWG +taxes. It came out to around 156 I think.
Check in: A+ four agents available, 3 busy. I was done in 2 minutes. Boarding: B+ Started early (40 minutes), boarded from the back by row, had everybody sittting for 15 minutes then before we moved to to late baggage. We left the gate 10 minutes early, but sitting for 15-20 was too long in summer heat. Seat: B My previous flight segment was in BA 1st, so a fair commparison cannot be made, however it was wider than a AC Y seat and had enough pitch that my legshad 2 inches between them and the next seat. and it was QUIET. The MD83 is super quiet, especially in 2A. There is a little card describing the features and it says the MD83 is actually 10 decibels quieter than the A320. I believe it. Pins could be heard dropping.

Overall good service, everything cost a buck or 2 except the booze. We arrived 15 minutes earlier into ywg, baggage claim was quick.

Excellent value.
