You have a Monday morning meeting in Dhaka. Your bag is packed, your plans are set, and now you are staring at four different airline options on your screen, wondering which one to go with. Sound familiar?

If you have ever stood at this crossroads before booking a Sylhet to Dhaka flight, you are definitely not alone. With four airlines currently operating on this route, each offering slightly different fares, baggage policies, and onboard experiences, making the right choice can feel oddly complicated for what is, at its core, a 45-minute journey.

That is exactly why we put this guide together. By the end of this article, you will know exactly which airline suits your travel style, your budget, and your expectations on the Sylhet to Dhaka route.

Why Flying from Sylhet to Dhaka Just Makes Sense

Let us be honest: the surface journey from Sylhet to Dhaka is no one's idea of a pleasant experience. Whether you take a bus or a train, you are looking at anywhere between 8 to 12 hours on the road or on the tracks. That is roughly half a day of your life before you have even started your work, family visit, or event in Dhaka.

By air, the Sylhet to Dhaka journey takes approximately 45 to 50 minutes from take-off to touchdown. For business travellers, NRBs visiting family, students returning to Dhaka, and increasingly for leisure travellers too, flying has quietly become the practical choice on this route, not just the expensive one.

And with Sylhet domestic flight fares Bangladesh-wide now quite competitive across all four carriers, the price gap between a flight and a long overnight bus may be smaller than you think.

Airlines Operating the Sylhet to Dhaka Route

Four airlines currently operate scheduled flights on the Sylhet to Dhaka route, departing from Osmani International Airport (ZYL) in Sylhet and arriving at Hazrat Shahjalal International Airport (DAC) in Dhaka.

Biman Bangladesh Airlines

The national carrier of Bangladesh has been operating on this route the longest and is the only airline among the four that uses Osmani International Airport as a hub. Biman offers multiple daily departures and remains a familiar, trusted option for millions of Bangladeshi travellers.

US-Bangla Airlines

Bangladesh's largest private carrier, US-Bangla Airlines operates the highest frequency of flights on this route, giving passengers more flexibility when it comes to departure times throughout the day.

NOVOAIR

A domestic-focused airline with a strong reputation for punctuality and in-cabin service quality, NOVOAIR has consistently been well-rated by frequent domestic flyers in Bangladesh.

Air Astra

The newest entrant in Bangladesh's domestic aviation sector, Air Astra launched its Dhaka to Sylhet service in February 2023. Despite being the youngest airline on this list, it has quickly built a following among travellers who value a modern, quiet cabin experience.

Sylhet to Dhaka Flight Ticket Price Comparison

Here is where things get interesting. Based on the latest one-way starting fares available on ShareTrip, this is how the four airlines stack up:

Airline	One-Way Starting Fare (BDT)	Checked Baggage	Cabin Baggage
Biman Bangladesh Airlines	৳5,008	20 kg	7 kg
NOVOAIR	৳5,218	20 kg	7 kg
Air Astra	৳5,561	20 kg	7 kg
US-Bangla Airlines	৳5,566	20 kg	7 kg

Note: Fares are subject to change based on availability, booking date, and season. Always check live prices on ShareTrip for the most current rates.

What stands out immediately is just how close these fares are. The gap between the lowest fare (Biman at ৳5,008) and the highest starting fare (US-Bangla at ৳5,566) is a mere ৳558. That is a difference smaller than a decent restaurant meal in Dhaka.

On the baggage front, all four airlines offer exactly the same allowance on their domestic economy fares: 20 kg of checked baggage and 7 kg of cabin baggage. So the baggage comparison is, quite literally, a draw.

Airline by Airline: A Closer Look

Fares shift frequently. What does not shift quite as fast is the overall travel experience. Here is what each airline genuinely brings to the table beyond the headline fare.

Biman Bangladesh Airlines

Biman is the most affordable starting point on this route at ৳5,008, and for many Bangladeshi travellers, the familiarity of flying with the national carrier is a comfort in itself.

Aircraft on this route: Biman operates Bombardier Q400 turboprop aircraft on shorter domestic sectors
Frequency: Multiple daily departures with a wide spread of timings
Baggage allowance: 20 kg checked + 7 kg cabin on economy class
Cabin experience: Functional and reliable; cabin crew are generally courteous
Best for: Travellers who want the lowest entry fare, prefer the national carrier, or are frequent Biman flyers

One honest note: Biman's punctuality on domestic routes has historically been inconsistent. If your Dhaka arrival is time-sensitive, that is worth factoring in.

US-Bangla Airlines

US-Bangla is Bangladesh's largest private airline and operates the highest number of daily flights on the Sylhet to Dhaka route. That frequency is arguably its strongest selling point.

Aircraft on this route: ATR 72-600 with a 2-2 seating configuration (no middle seats)
Frequency: Approximately 6 flights daily, giving you the widest range of departure windows throughout the day
Baggage allowance: 20 kg checked + 7 kg cabin on economy class
Cabin experience: Complimentary refreshments served onboard; in-flight reading available
Excess baggage fee: BDT 100 per kg on domestic routes
Best for: Travellers who need a specific departure time or who fly this route regularly

At ৳5,566, US-Bangla's starting fare is the highest on this list. But if you have a schedule to stick to and need a particular departure slot, the frequency advantage can easily justify the small premium.

NOVOAIR

NOVOAIR has built a genuine reputation as one of Bangladesh's most customer-friendly domestic airlines, with consistent praise for punctuality and in-cabin service.

Aircraft on this route: ATR 72-500 aircraft with up to 70 seats
Frequency: Multiple daily flights on the Sylhet to Dhaka route
Baggage allowance: 20 kg checked + 7 kg cabin on economy class
Cabin experience: Clean interiors, attentive cabin crew, and a strong track record for on-time departures
Best for: Travellers who want a reliable schedule and a slightly more polished domestic flying experience

At ৳5,218, NOVOAIR sits just ৳210 above Biman. For that small difference, you typically get a meaningfully better experience.

Air Astra

Air Astra is Bangladesh's newest domestic airline, and while it may lack the decades of history that Biman carries, its fleet is the most modern among the four airlines on this route.

Aircraft on this route: ATR 72-600, the newest aircraft type among the four carriers
Seating: 2-2 configuration with leather seats; no middle seats, quieter cabin
Baggage allowance: 20 kg checked + 7 kg cabin on economy class
Cabin experience: Complimentary bottled water provided; modern, clean, and noticeably quiet due to the newer aircraft engines
Excess baggage fee: BDT 150 per kg on domestic routes
Best for: First-time flyers, solo travellers, and business commuters who prioritise a quiet and comfortable ride

Air Astra's starting fare of ৳5,561 is practically identical to US-Bangla's, but the cabin experience is distinctly different thanks to the newer fleet.

Price Is Not Everything: Other Factors Worth Considering

When comparing the Sylhet to Dhaka flight ticket price across all four airlines, it is tempting to go straight for the cheapest fare. Before you do, here are a few other factors worth keeping in mind.

Departure timing: The cheapest fare means nothing if the only available slot does not suit your schedule. US-Bangla's high daily frequency gives you the most options.
Punctuality: If you have a meeting, a ceremony, or a connecting journey in Dhaka, a late departure is a real problem. NOVOAIR has a stronger punctuality record than most.
Excess baggage costs: If you are travelling with extra luggage, the advertised fare may not reflect your final total. Air Astra charges ৳150 per kg for excess domestic baggage, while US-Bangla charges ৳100 per kg.
Cabin comfort over time: For a single 45-minute flight, comfort might seem like a minor detail. But for frequent flyers doing this route weekly or fortnightly, a quieter and more comfortable cabin does add up over time.
Travel protection add-ons: When booking through ShareTrip, you can add Refund Guard, Travel Insurance, and Baggage Protection to any of these flights at checkout. These add-ons give you financial peace of mind regardless of which airline you choose, and they are particularly worth considering during peak travel seasons.

Our Honest Verdict: Which Airline Is Best for the Sylhet to Dhaka Route?

There is no single "best" airline here because the right choice genuinely depends on what matters most to you. Here is a clear breakdown:

Best for budget travel: Biman Bangladesh Airlines (from ৳5,008). The lowest starting fare by a clear margin.
Best for schedule flexibility: US-Bangla Airlines. No other carrier on this route gives you as many departure time options each day.
Best for reliability and punctuality: NOVOAIR. Consistently well-rated by frequent domestic travellers in Bangladesh.
Best for cabin comfort and modern fleet: Air Astra. The ATR 72-600 with leather seating and a 2-2 cabin layout offers the most comfortable domestic flying experience on this route.
Best overall value for most travellers: NOVOAIR. At just ৳210 more than Biman, the improvement in experience is difficult to argue against.
