JetBlue Airlines: Flight Tracking, Baggage Fees & WiFi Guide

Whether you are a frequent JetBlue flyer or booking your first flight with them, this guide covers everything you need to know about tracking your flights, understanding baggage policies, staying connected with WiFi, and more.

Track Your JetBlue Flight in Real-Time

Waiting for a flight can be stressful, especially when you are picking someone up from the airport or trying to make a tight connection. JetBlue flight tracking helps you stay updated on:

1. Current flight status - delays, cancellations, or on-time departures
2. Gate information - know exactly where to go at the airport 
3. Baggage claim details - which carousel to head to when you land
4. Real-time location - see where your plane is during the flight 

How to Track JetBlue Flights

You have several options for tracking JetBlue flights:

On JetBlue's Website or App:

Using FlyFi App Flight Tracker:

Search by Flight Number: Just enter your JetBlue flight number (for example, B6123) to instantly check your flight status and live location.

Scan Your Boarding Pass: The fastest way to track. Scan the barcode on your JetBlue boarding pass (digital or printed), and FlyFiApp will automatically track your journey from start to finish.

Download FlyFiApp for iOS or Android to start tracking flights with ease.

JetBlue Baggage Policy & Current Fees

JetBlue's baggage policy is more generous than ultra-low-cost carriers but varies by fare class. Understanding these rules prevents surprise fees at check-in.

Carry-On Rules (Always Free)

Every JetBlue ticket includes:

1. One personal item: 17" × 13" × 8" (fits under seat) — purse, laptop bag, small backpack
2. One carry-on bag: 22" × 14" × 9" (overhead bin) — roller bag or larger backpack

This applies to all fare types, including Blue Basic. No fees, no restrictions beyond size limits.

Checked Baggage Fees by Fare Type

Fees vary by route and booking timing. International flights may have different rates. Check JetBlue.com when booking for exact pricing.

Weight and Size Limits

1. Standard bags: Maximum 50 lbs and 62 linear inches (length + width + height)
2. Overweight (51-99 lbs): Additional $150 fee
3. Oversized (63-80 inches): Additional $150 fee
4. Both overweight AND oversized: $150 fee applies once, not twice

Special Items at No Extra Cost

When traveling with children, these don't count toward your baggage allowance:

1. Car seats and booster seats
2. Strollers (gate-check available)
3. Diaper bags
   

Cost-Saving Insight: If you are on the edge between Blue Basic and Blue, calculate whether the checked bag fee exceeds the fare difference. On many routes, upgrading to Blue costs less than paying for a checked bag, plus you get seat selection and earlier boarding.

JetBlue WiFi: How Fly-Fi Works

JetBlue's free high-speed WiFi (branded as "Fly-Fi") is available on most of their fleet. This is satellite-based internet that works throughout the flight.

Aircraft Coverage

Fly-Fi is installed on:

1. All Airbus A321 aircraft
2. All Airbus A220 aircraft
3. Most Airbus A320 aircraft (check during booking if critical)
