Last Updated: July 2026

Editorial Review: This guide has been reviewed by the FlyTripInfo editorial team using publicly available Singapore Airlines seating information. We aim to provide clear, independent travel guidance to help you make informed decisions before your flight.

Quick Answer

Yes, you can choose your seat on Singapore Airlines. Whether it’s free depends on your cabin, fare type, and KrisFlyer membership status. Business Class, First Class, and Suites passengers can choose seats free of charge. In Economy, Standard seats are included with most fares, while Economy Lite passengers may need to pay for advance seat selection. Extra Legroom and Premium Economy Solo seats usually cost extra.

If you don’t want to pay, you can usually choose from the remaining available seats once online check-in opens 48 hours before departure.

This guide explains how seat selection works, when you’ll pay a fee, how upgrades work, and how to choose the best seat for your trip.

Can You Choose Your Seat on Singapore Airlines?

Yes. You can reserve your seat during booking, after booking, or when online check-in opens.

There are three ways to select your seat:

1. During booking – Choose your preferred seat while purchasing your ticket.
2. After booking – Log in to Manage Booking on the Singapore Airlines website or app to change or reserve your seat.
3. During online check-in – Remaining available seats can usually be selected when check-in opens 48 hours before departure.

If your preferred seat isn’t available when you book, check again later. Aircraft changes or passenger cancellations sometimes open up more seats before departure.

Is Singapore Airlines Seat Selection Free?

It depends on the fare you buy.

Business Class, First Class, and Suites passengers receive complimentary seat selection. Economy passengers may receive free Standard Seat selection depending on their fare, while premium seating options usually require an additional payment.

In general:

• Economy Lite may charge for advance seat selection.
• Economy Value, Standard, and Flexi include Standard Seat selection.
• Premium Economy includes Standard Seats.
• Extra Legroom and selected Premium Economy seats usually cost extra.

If you’re unsure, your booking confirmation or the seat map in Manage Booking will show whether a fee applies.

How Do You Choose a Seat After Booking?

You don’t need to contact customer service to select a seat. Most passengers can do it themselves online.

Steps to reserve a seat

1. Visit the Singapore Airlines website or open the mobile app.
2. Open Manage Booking.
3. Enter your booking reference and last name.
4. Open the seat map.
5. Choose your preferred available seat.
6. Pay any applicable fee and save your selection.

You can return to Manage Booking later if you’d like to change your seat before check-in, subject to availability.

What Seat Options Are Available?

Singapore Airlines offers several seating options depending on your aircraft and cabin.

Seat Type	Best For	Extra Fee
Standard Seat	Most travellers	Sometimes
Extra Legroom Seat	More comfort on longer flights	Yes
Premium Economy Solo Seat	Extra privacy	Yes
Business, First & Suites	Premium travel experience	Included with ticket

Standard Seats

These are the regular seats available throughout the cabin. Many Economy fares include them at no additional cost.

Extra Legroom Seats

These seats provide more space to stretch your legs and are a good choice for overnight or long-haul flights.

Premium Economy Solo Seats

Available on selected aircraft, these seats offer more privacy and are popular with solo travellers. They usually cost more than regular Premium Economy seats.

Which Singapore Airlines Seats Are Best?

The best seat depends on your travel style rather than your ticket.

Here are some general recommendations:

• Window seat – Best for sleeping and enjoying the view.
• Aisle seat – Ideal if you like getting up frequently.
• Extra Legroom seat – Worth considering on flights longer than 8 hours.
• Premium Economy Solo seat – A good choice if you want more privacy.
• Seats near the front – Help you leave the aircraft sooner after landing.
• Families – Reserve seats early to improve your chances of sitting together.

If you’re taking a short regional flight, a Standard Seat is usually enough. For longer journeys, paying a little extra for more legroom can make the flight much more comfortable.

Can You Choose a Seat for Free During Online Check-in?

Yes. Once online check-in opens 48 hours before departure, Singapore Airlines usually lets passengers choose from the remaining available seats at no extra cost.

This is a good option if you don’t mind where you sit and want to avoid paying an advance seat selection fee. However, the most popular seats, such as window seats, aisle seats, or Extra Legroom seats, may already be taken.

If sitting in a specific seat is important, it’s better to reserve it earlier.

How Can You Upgrade Your Seat?

Singapore Airlines offers several ways to move to a higher cabin, but upgrades always depend on availability.

You may be able to upgrade by:

• Redeeming KrisFlyer miles
• Paying the fare difference
• Using mySQupgrade, Singapore Airlines’ upgrade bidding program (available on eligible bookings)

Upgrade Options at a Glance

Upgrade Method	Best For
KrisFlyer Miles	Frequent flyers with enough miles
Fare Difference	Guaranteed upgrade (subject to availability)
mySQupgrade	Travellers looking for a lower-cost upgrade

KrisFlyer Miles

If you have enough KrisFlyer miles, you may be able to upgrade from Economy to Premium Economy or Business Class, depending on your ticket and available upgrade inventory.

Pay the Fare Difference

You can sometimes upgrade by paying the difference between your current ticket and the higher cabin fare. This is usually the most straightforward option if seats are available.

mySQupgrade

Eligible passengers may receive an invitation to bid for an upgrade before departure.

Here’s how it works:

1. Receive an invitation from Singapore Airlines.
2. Submit your bid.
3. Wait for the airline to review bids before departure.
4. If your bid is accepted, your payment is processed and your cabin is upgraded.

Since this is a bidding system, submitting a bid does not guarantee an upgrade.

Do KrisFlyer Members Get Better Seat Benefits?

Yes. KrisFlyer members with elite status often receive additional seat selection benefits, although these depend on their membership tier.

Benefits may include:

• Complimentary seat selection on more fare types
• Access to additional seat categories
• Better upgrade opportunities using KrisFlyer miles
• Priority services available to elite members

If you’re a frequent Singapore Airlines traveller, linking your KrisFlyer number to your booking before selecting a seat can unlock extra benefits.

What Happens If You Don’t Select a Seat?

Singapore Airlines will automatically assign a seat before your flight.

Most passengers receive a seat assignment during online check-in or before boarding.

If you don’t like the assigned seat, you may still be able to change it during online check-in if other seats are available.

For families or groups, selecting seats early gives you a better chance of sitting together.

Is Paying for Seat Selection Worth It?

The answer depends on your trip.

It may be worth paying if:

• You’re taking a long-haul flight.
• You want extra legroom.
• You’re travelling with family.
• You prefer a window or aisle seat.
• You need to sit near the front of the aircraft.

You can probably skip the extra fee if:

• You’re on a short regional flight.
• You’re flexible about where you sit.
• You plan to choose a seat when online check-in opens.

Practical Tips Before You Fly

• Check your fare to see if seat selection is already included.
• Reserve seats early if you’re travelling with family or friends.
• Use Manage Booking if you want to change your seat after booking.
• Check in as soon as online check-in opens for more free seat options.
• Compare the cost of an Extra Legroom seat with the cost of upgrading your cabin before making a decision.
• If you’re using KrisFlyer miles, check upgrade availability well before your travel date.

Common Travel Scenarios

You’re flying on an Economy Lite fare

Advance seat selection may cost extra. If you don’t have a preferred seat, wait until online check-in opens and choose from the remaining available seats.

You’re travelling with your family

Reserve seats as early as possible. Waiting until check-in may reduce the chances of sitting together.

You’re taking a long international flight

An Extra Legroom seat or Premium Economy upgrade may be worth the extra cost for added comfort.

You have KrisFlyer miles

Before paying for a seat or upgrade, check whether you can use your miles instead. This may offer better value than paying cash.

Before You Book
