"Please select other flights and proceed."

Has anyone else received this error when trying to finalizing flight bookings (payment stage) on JetBlue.com of late?

It has happened the last three itineraries that I've booked (er... attempted to book) within the last eight days.

It happens on different browsers, and with different payment methods (Visa, PayPal, etc.). Nothing indicated it's a client side issue.

There is plenty of availability on the flight and fare level, and a call into 1-800-JETBLUE results in the exact same fare.

It's really maddening.

Making matters worse, the first two times I called into 1-800-JETBLUE the agent accommodated the situation and gladly waived the $15 over-the-phone booking fee. But just now - the third time this error has occurred - I was told I had to get transferred to crew member support if I wanted the fee waived. So I'm on hold yet again (30+ minutes and counting) Lovely.

I've flown just about one round trip a week on B6 this calendar year. The in flight experience on B6 is great, but outside of that I'm getting more and more underwhelmed. If B6 can't build an online booking system that works properly and treats their loyal customers this poorly then perhaps I need to consider giving my business to another airline.
