Booking Flights with HDFC Reward Points: Step-by-Step Guide

Bottom Line: The best way to book flights with HDFC reward points is through the SmartBuy portal for domestic flights (straightforward, decent value) or by transferring points to airline partners like Singapore KrisFlyer or British Airways Avios for international premium cabin redemptions where you can extract 2–5x more value per point.

Why HDFC Reward Points Are Worth Your Attention

HDFC Bank sits on one of the most versatile reward ecosystems in Indian banking. Depending on which card you hold — Regalia, Infinia, Diners Club Black, or even the Millennia — your points carry different weight. But the mechanics of turning those points into a boarding pass remain largely the same.

The trouble is, most cardholders either let points expire or blow them on Amazon gift vouchers worth Rs 0.20 per point. Flight redemptions, done right, can fetch you Rs 0.50–1.50 per point. That’s a 3–7x difference in value.

Let’s break down exactly how to do it.

Two Ways to Book Flights with HDFC Points

You have two distinct paths. Which one you pick depends on whether you’re flying Delhi–Mumbai or Delhi–London.

Option 1: Book Directly on SmartBuy

This is the simplest route. HDFC’s SmartBuy portal is essentially a travel booking engine (powered by ClearTrip/EaseMyTrip) where you can pay partially or fully with reward points.

Step-by-step:

Go to SmartBuy and log in with your HDFC net banking or credit card credentials
Search for your flight — domestic or international
Select your flight and proceed to the booking page
On the payment page, you’ll see the option to “Pay with Reward Points”
Enter how many points you want to redeem (the portal shows the rupee equivalent)
Pay any remaining balance with your HDFC credit card
Complete the booking — confirmation lands in your inbox

What you need to know:

Redemption value on SmartBuy is typically 1 point = Rs 0.30 for most cards
Infinia and Diners Club Black cardholders get 1 point = Rs 1.00 on SmartBuy — a massive difference
You can use points for partial payment (say, 5,000 points + rest on card)
SmartBuy prices are generally at par with other OTAs, sometimes slightly higher

Option 2: Transfer Points to Airline Partners

This is where serious value extraction happens. HDFC lets you transfer reward points to 15 airline loyalty programmes and 6 hotel programmes. The transfer ratio varies by card tier.

Step-by-step:

Log in to HDFC NetBanking → Cards → Reward Points → Transfer to Partners
Select your airline partner (e.g., Singapore Airlines KrisFlyer, Air France-KLM Flying Blue, British Airways Avios)
Enter the number of points to transfer (minimum thresholds apply)
Provide your airline loyalty programme membership number
Confirm the transfer — points typically land in 2–5 business days
Book your award flight directly through the airline’s website

Transfer Ratios and Value: The Comparison Table

Card	SmartBuy Value	Transfer Ratio (Airline Miles)	Best Use Case
Infinia	1 pt = Rs 1.00	1:1 (most partners)	International business class via partners
Diners Club Black	1 pt = Rs 1.00	1:1 (most partners)	Same as Infinia — premium redemptions
Regalia / Regalia Gold	1 pt = Rs 0.30	2:1 (2 pts = 1 mile)	SmartBuy domestic flights
Millennia	1 pt = Rs 0.20	Not eligible for most transfers	SmartBuy only, consider cashback instead
MoneyBack+	1 pt = Rs 0.20	Not eligible	Better off with statement credit

The gap is stark. An Infinia cardholder transferring 10,000 points to KrisFlyer gets 10,000 miles — enough to cover a one-way Singapore flight in economy. A Regalia cardholder would need 20,000 points for the same 10,000 miles.

Best Airline Partners for Indian Travellers

Not all 15 transfer partners are equally useful. Here’s where Indians get the most bang:

Singapore Airlines KrisFlyer

Transfer at 1:1 (Infinia/DCB). Excellent for Southeast Asia. Watch for KrisFlyer Spontaneous Escapes — monthly discounted award seats that can slash requirements by 30–50%. Great for BLR/DEL/BOM to Singapore, Bangkok, Bali.

British Airways Avios

Strong for short-haul flights — the Avios distance-based chart rewards short routes disproportionately. Mumbai to Goa on a partner airline can cost just 6,000 Avios one-way. Also useful for Qatar Airways business class bookings to Europe.

Air France-KLM Flying Blue

Dynamic pricing, which is a double-edged sword. During Promo Rewards (monthly flash sales), you can find Europe flights for 50% off standard rates. Worth stalking if you plan ahead.

InterMiles (Jet Airways successor programme)

Useful for domestic flights on IndiGo and other partners. Lower sweet spots than SmartBuy if you time it right.

When SmartBuy Beats Transfer Partners (and Vice Versa)

Use SmartBuy when:

You’re booking a domestic flight (DEL–BOM, BLR–CCU, etc.)
You hold Infinia or DCB (Rs 1/point makes it simple and competitive)
You need to book quickly — no waiting for transfer processing
The cash price of the ticket is low (under Rs 5,000)

Use transfer partners when:

You’re eyeing international premium cabins (business or first class)
The cash ticket price exceeds Rs 30,000–40,000
You hold Infinia/DCB and can transfer at 1:1
You’ve spotted a partner airline sweet spot or promo

Common Mistakes to Avoid

Redeeming on the HDFC rewards catalogue for flights — The catalogue often gives worse value than SmartBuy. Always compare.
Transferring points from a Regalia at 2:1 — Unless you’re targeting a very specific high-value redemption, the 50% haircut on transfer makes SmartBuy the better bet for Regalia holders.
Ignoring fuel surcharges on award tickets — Airline award bookings still charge taxes and surcharges. A “free” BA ticket to London can carry Rs 15,000–25,000 in surcharges. Flying Blue and KrisFlyer typically have lower surcharges.
Letting points expire — HDFC points expire 2–3 years after earning (varies by card). Set a calendar reminder.

Frequently Asked Questions

How many HDFC reward points do I need to book a domestic flight?

It depends on the ticket price and your card. On SmartBuy with an Infinia card (1 pt = Rs 1), a Rs 4,000 Delhi–Mumbai flight costs 4,000 points. With a Regalia (1 pt = Rs 0.30), you’d need around 13,300 points for the same flight.

Can I use HDFC reward points for international flights?

Yes — either through SmartBuy (works for international bookings) or by transferring points to airline partners like KrisFlyer, Flying Blue, or Avios for award ticket redemptions on international routes.

How long does it take for transferred points to appear in my airline account?

Typically 2–5 business days, though it can occasionally take up to 7 days. Don’t transfer points if you need to book an award seat urgently — it might get taken before your miles land.

Do HDFC reward points expire?

Yes. Most HDFC credit card reward points expire 2 to 3 years from the date of earning. The exact policy varies by card variant. Check your monthly statement or NetBanking for expiry dates.

Is SmartBuy more expensive than other booking platforms?

SmartBuy prices are generally competitive with MakeMyTrip, EaseMyTrip, and ClearTrip. Occasionally they’re Rs 100–300 higher on certain routes. The reward point redemption value usually more than compensates for any small price difference.

Which HDFC card gives the best value for flight bookings?

The HDFC Infinia and Diners Club Black are in a league of their own — 1:1 transfer ratio and Rs 1/point on SmartBuy. If you don’t qualify for these (they typically need Rs 10L+ annual income or relationship value), the Regalia Gold offers a middle ground, though at lower per-point value.
