KIA-4 HAL to airport road bus timings

KIA-4 Bus Timings: HAL Airport Road to Bangalore Airport (BLR)

Last Updated: February 19, 2026 | Route: Vayu Vajra KIA-4 (Via Marathahalli & Hebbal)

The KIA-4 is the most reliable link for residents of HAL, Marathahalli, and Indiranagar heading to the airport. At a fixed fare of approximately ₹240 - ₹260, it offers a premium AC experience while bypassing the city's central congestion. Whether you are starting from the HAL Main Gate, Marathahalli, or the surrounding ISRO and DRDO campuses, the KIA-4 is strategically positioned to pick up travelers from these high-traffic points. The route typically winds through Marathahalli, Hebbal, and finally onto the Airport Road. It bypasses the more congested central business district, making it one of the more efficient ways to traverse the city's eastern corridor toward the northern periphery.

• The "Indiranagar" Shortcut: If you are staying in Indiranagar or Domlur, take the Purple Line to Indiranagar Metro Station. The KIA-4 stop is a 2-minute walk from the station (near the KFC junction).
• Travel Hack: Avoid the Marathahalli bridge traffic by taking the Metro to Indiranagar and boarding the KIA-4 there.

Arrival and Departure at Kempegowda International Airport (BIAL)

Navigating the Airport Bus Bays

Upon reaching the airport, the bus will drop you right at the departure ramp. For your return journey, head to the BMTC Bus Hub, located just a short walk from the arrivals hall. Look for the "KIA-4" lane.

Connecting to Your Flight

The walk from the bus drop-off point to the check-in counters is less than five minutes. Trolleys are usually available right where the bus parks.

Frequently Asked Questions (FAQs)

1. Does the KIA-4 bus stop at both Terminal 1 and Terminal 2?

Yes. The KIA-4 service stops at the designated bus bays for both Terminal 1 (Domestic) and Terminal 2 (International & Select Domestic). If you are unsure which terminal your flight departs from, ask the conductor as you approach the airport.

2. Can I pay for my ticket using UPI (PhonePe, GPay, Paytm)?

Yes, BMTC has equipped almost all Vayu Vajra (Volvo) buses with UPI QR codes. You can scan the QR code provided by the conductor or located on the bus window. It is still recommended to carry a small amount of cash as a backup in case of network issues.

3. Is there a night bus for this route?**

The KIA-4 operates nearly 24/7. However, for travel between 1 AM and 4 AM, the frequency is lower. We recommend checking the Namma BMTC app for live tracking.

4. How long does KIA-4 take from HAL to Airport?

Usually 1 to 2 hours depending on traffic.

5. Where can I board KIA-4 near Indiranagar?

Major access points include HAL Main Gate, Kodihalli, Domlur, and near Indiranagar 100 Feet Road connections.

6. Is there an extra charge for luggage?

No. Unlike standard BMTC buses, the Vayu Vajra premium service includes luggage in the ticket price. These buses are specifically designed with internal luggage racks to accommodate large suitcases.

7. Can non-airport travelers use the KIA-4 bus?

Yes. While the primary purpose is airport connectivity, anyone can board the KIA-4 for local travel within the route (e.g., from HAL to Hebbal). However, be aware that you will be charged the premium Vayu Vajra fare, which is higher than a regular AC Volvo (Vajra) ticket.

8. What is the frequency of the KIA-4 bus from HAL?

The KIA-4 typically runs every 30 to 45 minutes during peak hours and approximately every hour during late-night or very early-morning shifts.

9. What should I do if I miss the last KIA-4 bus?

The KIA-4 operates nearly 24/7, with very few gaps in the early morning hours. If you face a long wait, your best contingency plan is to take a local bus or cab to Marathahalli Bridge or Hebbal, where more frequent airport routes (like KIA-8 or KIA-9) converge.

Plan B: What if I miss the KIA-4?

Since the KIA-4 has a slightly lower frequency during the afternoon, keep these contingency plans ready:

• The "Marathahalli" Pivot: Take a quick auto to Marathahalli Bridge. From here, you can board the KIA-8 (from Electronic City) or KIA-6 (from Kadugodi), which both pass through this point every 15-20 minutes.
• The "Hebbal" Hub: If you are already in North Bangalore, take any local bus to Hebbal Bridge. All Vayu Vajra buses (KIA-5, 8, 9, 14) stop here, ensuring a bus to the airport every 5 minutes.
• Taxi via ORR / Hebbal... Fast but expensive during peak surge.
• Metro to Majestic + Airport Bus. Take Purple Line → Majestic → Board airport bus from there.

Alternate airport routes

If a KIA-4 bus is significantly delayed, your best backup is to take a local bus to Marathahalli Bridge or Hebbal, where multiple other airport lines (like KIA-8 or KIA-9) converge, increasing your chances of a quick pick-up. If you find yourself further north, near Indiranagar or K.R. Puram, you might encounter KIA-6 or KIA-8. However, for the core HAL/Marathahalli area, the KIA-4 remains the most direct and frequent option.
