Changing seat on second segment
 

I am flying BOS-SFO-BOS on JBU. Flew out here the other day, flying back on Friday. I have a middle seat for my return flight, and I'd like to change it. Prior to flying out here, I had the option to change seats on the website, but now when I log in to manage my flight, the I don't have the option. How can I go about trying to change my seat?

Call them. Their phone agents are helpful :)
Edit: caliform mentioned Twitter; they are also quick to reply on Facebook (~1 hour response time).

+1 on the phone, also try Twitter if you have an account. They're very quick to reply.

I called em, and I got an aisle seat. Thanks all!

So wait, it's impossible to change the seat via the JetBlue website on any successive segments of an itinerary after being checked-in? (The option is currently greyed out for me - found this thread via search.)

Was it a "Blue Minus" fare?

Usually the website seat map is only locked out when you're actively checked into one of the flights on the itinerary. But a quick gander around these parts will reveal that JetBlue's website doesn't always function exactly as it's supposed to.

No, it's a Mint r/t. :o

I'm currently checked-in for the outbound of a r/t itinerary. Will the seat map for the inbound become "unlocked" once the outbound flight departs (or completes)?

This seems like a huge system limitation....

If you're checked in for a flight, you cannot modify. You can uncheck yourself in, modify and then check in again.

I'd also suggest the chat function on the website, assuming the wait time isn't too long. I was in a similar dilemma in September and they sorted it out in a few minutes.
