San Diego → New York

Why this is a good fare

Transcontinental round trips this low are uncommon outside of sales. JetBlue includes a carry-on and roomier seats, so the all-in cost stays close to the headline price.

Things to check before booking

• Confirm the exact dates and times on the partner site before you book — sample fares can shift with real-time availability.
• Add the bag you actually plan to bring and compare the all-in total, not just the base fare.
• Check the airline's change and cancellation terms for this fare class.
• Look at the outbound and return times — very early or very late departures are often what makes a fare cheap.
