+
+## **4. Key Comparisons**  
+
+### **4.1 Distance Efficiency**  
+| **Route**          | **Shortest Distance** | **Longest Detour** |
+|--------------------|----------------------|--------------------|
+| **KAUS → KDAL**    | 217 sm               | 716 sm             |
+| **KDAL → KAUS**    | 200 sm               | 761 sm             |
+| **KAUS → KDFW**    | 217 sm               | 918 sm             |
+| **KDFW → KAUS**    | 195 sm               | 648 sm             |
+
+**Takeaway:**  
+- **KDFW ↔ KAUS is the most efficient** (195–217 sm).  
+- **KDAL routes are slightly longer** due to airspace constraints.  
+
+---
+
+### **4.2 Altitude Trends**  
+| **Direction**      | **Typical Altitudes** | **Notes**                     |
+|--------------------|----------------------|------------------------------|
+| **KAUS → KDAL**    | 17,000–FL300         | Low-altitude corridor.        |
+| **KDAL → KAUS**    | 13,000–FL260         | Similar low-altitude profile. |
+| **KAUS → KDFW**    | 12,000–FL280         | Optimized for short hops.     |
+| **KDFW → KAUS**    | 15,000–FL300         | Slightly higher than KDAL.    |
+
+---
+
+### **4.3 Outliers & Detours**  
+- **Long Detours (500+ sm):**  
+  - `AEROZ2 SJT HNKER VKTRY2` (564 sm, KAUS→KDFW).  
+  - `KKITY5 DOSXX SJT JCT SAT BELLR6` (761 sm, KDAL→KAUS).  
+- **Weather Avoidance:**  
+  - Routes via **SJT/JCT** suggest central Texas weather reroutes.  
+
+---
+
+## **5. Recommendations**  
+### **Optimal Routes**  
+| **Direction**      | **Best Route**                  | **Distance** | **Altitude** |
+|--------------------|-------------------------------|-------------|-------------|
+| **KAUS → KDAL**    | `SAYBR3 SAYBR CHEVE MNNDO4`   | 217 sm      | FL250       |
+| **KDAL → KAUS**    | `RAMBL6 WINDU SEWZY6`         | 200 sm      | FL220       |
+| **KAUS → KDFW**    | `ELOEL3 FORSS GUTZZ SOCKK4`   | 217 sm      | FL240       |
+| **KDFW → KAUS**    | `JASPA7 WINDU SEWZY6`         | 195 sm      | FL250       |
+
+### **Avoid Unless Necessary**  
+- **SJT/JCT** routes (add 300+ sm).  
+- **ABI/SPS** detours (500+ sm).  
+
+---
+
+## **6. Conclusion**  
+- **KDFW ↔ KAUS is the most efficient** (195–217 sm).  
+- **KDAL routes are slightly longer** but still optimized.  
+- **Low-altitude corridors (12,000–FL300)** dominate for short-haul flights.  
+
+**Next Steps:**  
+- Real-time wind optimization.  
+- Weather-related reroute analysis.
