On July 2 we flew back from JFK to SFO. The flight arrived 9 hours late. JetBlue gave us a compensation of $150 valid for 6 months. I want to appeal that on two grounds:

I believe that for a delay of more than 6 hours the compensation should be $250, according to JetBlue's own guidelines.

The compensation should be valid for more than 6 months.

I have tried to reach JetBlue and had absolutely no success in either reaching the chat room or a live voice. Any suggestions?

Were you sitting on the plane for 9 hours? Normally they will return to the gate within 3 hours if that is the case.

If the delay was announced before you boarded it is $150.

The plane had air conditioning problems, so we were delayed while the technicians tried to fix it. Eventually we took off and we must have been over Pennsylvania when the pilot announced that we were returning to JFK. We sat on the ground for a while and then we received $12 meal vouchers and were told to deplane and stick around for the new plane. We eventually boarded the new plane, and still did not move when the new pilot announced that according to FAA rules he could not fly the plane because it would exceed his hours of flight time and they were looking for a new pilot. Eventually they found one and we took off to arrive at SFO nine hours later than scheduled.

I can see your point but it sounds like Jetblue is going by the rule that your first delay was announced before you boarded, apparently. I have no idea about the validity time thing, I don't see that on their website. From what I've seen, there are no Federal laws covering flight delay compensation, only cancellations. Good luck, I suppose you can complain to DOT or their social nedia page on X or Facebook.

The first delay was announced after the scheduled departure while we were sitting at the gate.

"JetBlue has an escalating compensation structure. The minimum compensation is $50 in travel credits after a three-hour departure delay, and the credit adjusts upward by $50 for every additional hour. The credit maxes out at $200 for delays of six hours or more.
Once passengers have boarded the aircraft, the compensation structure is $100 in credit for a delay between three and five hours, $175 in credit for a delay between five and six hours, or a $250 credit for a delay of six hours or more."

Trying to reach a real person is impossible. Any suggestions in that regard?

FlyerTalk has an entire JetBlue forum with thousands of members. I'd ask for assistance/suggestions there . . .

Thanks. I hope to have more success there, at least get an agent's attention.
