Airline

Each airline in the directory has its own page, from Bangladesh's own carriers to airlines based in the Gulf, Asia, Europe, Africa and the Americas. The four Bangladeshi airlines and the main foreign carriers serving Dhaka are in the airline cards at the top of this page.

Yes. Every airline page has a flight search for one-way, round-trip and multi-city trips, with up to five flights and nine passengers. The results show that airline next to the other carriers on the same route, so you can see whether it is the best value for your dates. You can also start from the main flight search.

No. bookingMentor is an independent travel service and is not affiliated with the airlines listed here. Reviews come from travellers, and the guides are written by our travel team from each airline's official website and published airline records. Always confirm the details of your own booking with the airline.

Each guide answers the questions people have before they fly with that carrier:

• IATA and ICAO codes, the main hub and other airports it flies from
• Destinations grouped by region and its most popular routes
• Fleet, cabin classes and the frequent flyer programme
• Baggage rules, check-in steps and ways to pay less for tickets
• Traveller reviews and a questions section

All four Bangladeshi airlines fly domestic routes, connecting Dhaka with Chattogram, Cox's Bazar, Sylhet and Saidpur, and most of these flights take between 50 minutes and just over an hour. The busiest domestic routes are among the trending flights on this page, with the airlines on each.

Log in to your bookingMentor account (or sign up), open the airline's page and choose Write a review. You give a star rating, the month you flew, who you travelled with, a short title and at least 100 characters on things like check-in, crew, seat comfort, food, punctuality or baggage. You do not need to have booked the flight through bookingMentor.

Yes. Use Ask a question in the reviews and questions area of the airline page; a question needs at least 10 characters. The bookingMentor travel team and travellers who have flown the airline answer it, and answered questions are shown on the page, so it is worth reading the existing ones first.

The IATA code has two characters and appears in flight numbers and on tickets. The ICAO code has three letters and is used mainly by air traffic control and flight-tracking services. Every airline card on this page shows both, so you can match a flight number to its carrier.

Each guide shows the date it was last reviewed and the sources it was checked against. Airlines add, pause and reschedule routes and change their fleets during the year, so treat destination lists as a guide and check the current schedule when you search for your dates.

On any airline page, scroll to Other Airlines, which lists carriers flying the same routes with their hub, IATA code and alliance. Each route page also lists every airline on that route with the flight time, and the flight search shows their fares side by side.

The baggage section of each airline page explains how that carrier sets its allowance, but the exact amount depends on your route, cabin and fare, and it is printed on your e-ticket. In the flight search on an airline page you can also choose how many cabin and checked bags each passenger needs. The search counts 7 kg per cabin bag and 20 kg per checked bag, and fares whose allowance the airline has not published are left out.

Airline guides include a Cheap tickets section with habits that tend to bring the fare down:

• Search a range of dates, as midweek departures are often cheaper than Fridays and Sundays
• Book well ahead for Eid, the Hajj and Umrah seasons and school holidays
• Compare fare types, because a fare that includes a checked bag can cost less than adding one later
• Join the airline's frequent flyer programme before you fly
