Le site jetblue.com est-il sûr ?

I had the possibility to cancel my flight within 24 hours, I did it but the refund process is taking more than a month, I had to contact them and opodo (booking company) almost daily. I am said that opodo will will keep a part of sum as commission and I will get my refund within 10 (more) days. Still didn't receive anything.

When they cancel flights, they don't do anything to help you. No hotel or meal vouchers, and you have to figure out alternative transportation yourself. Additionally, their Contract of Carriage doesn't seem to indicate that they'll book you a seat on a competing airline if they can't get you there themselves -- this is in contrast to most other airlines, which respect "Rule 240".
