FAQ

How can I print a bag tag for bluejet checked baggage? Can I print it at home?
You can only print your bag at check-in curbside, at an airport kiosk, or at the ticket counter.
Bag tags can only be printed at airports. No one can print bag tags for flights outside the airport.

 
The system is telling me to "See an agent at the airport." What does it want to say?
That means you have to reach the airport as soon as possible to show your reservation at the counter. There may be a delay in your flight, any wrong information, or you may be late for check-in.

I tried my best to get my boarding pass, but I was too late and missed my flight.
Just go and speak directly to the crew member regarding your flight rebooking.
Also, you missed the flight, and that's why you have to pay your boarding compensation; the reason will be whatever for your missing flight does not matter.
At the airport just visit the jet blue desk and ask them to rebook if you are inside security.
