How Early To Arrive At Changi Airport For Your Flight

Before finalising their packing and settling in for rest, many travellers consider the question: 'How long before my flight is scheduled should I aim to arrive at the airport?'

There's no single, universally applicable rule for airport arrival times, as it varies depending on factors like destination and individual travel preferences. While the common advice is to arrive three hours before international flights, this doesn't account for all the variables that might affect your travel day plans.

If you’re flying out of Changi, the three-hour rule for international flights is still a safe guideline — but many Singapore travellers say two hours is usually enough, especially if you’ve checked in online and are travelling light. For peak periods like school holidays, weekends, or if you’re flying long-haul with more baggage, arriving earlier is wise.

Check-in

Changi offers multiple ways to check in. Most travellers recommend using online check-in or the self-service kiosks around the terminals to save time. Bag-drop counters are quick, though queues can form during busy hours. Of course, manned check-in counters remain available if you prefer full service or are travelling with special requirements.

Immigration

Immigration is generally smooth at Changi, with automated clearance lanes available for Singaporeans, PRs, and eligible foreign travellers. It usually takes only 5–15 minutes to go through immigration, though manned counters can take longer during peak travel times.

Airport security

Unlike some airports, security checks at Changi happen at the boarding gate, not before immigration. This means you don’t have to queue twice, but you should factor in extra time near boarding. Security involves scanning carry-ons and personal checks; expect to remove laptops, large electronics, and liquids.

Boarding

Boarding typically starts 40–60 minutes before departure, depending on the airline and aircraft. Even if you have an assigned seat, early boarding helps secure overhead bin space. Gates at Changi can be a fair walk from the main terminal, so travellers recommend heading over at least 30 minutes before boarding closes.

Online check-in

Most airlines at Changi allow you to check in online 48–24 hours before departure. This lets you select seats, confirm travel details, and sometimes even generate a mobile boarding pass. For those with checked baggage, online check-in still saves time — you only need to drop off your bags at the designated counters.

FAST check-in

Changi’s Fast and Seamless Travel (FAST) system includes self-service kiosks for printing boarding passes and bag tags, plus automated bag-drop machines. These are available at Terminals 1, 2, and 3, and are especially useful if you’re travelling light or want to avoid queues at manned counters.

Early check-in

If you want extra peace of mind, Changi provides early check-in counters where some airlines let passengers check in their bags as early as 12–24 hours before flight time. This is handy if you’d like to explore Jewel or the airport before your trip without lugging baggage around. Availability varies by airline, so always remember to check ahead.

Group check-in

For large parties travelling together, airlines provide dedicated group check-in counters at Changi. This helps streamline the process for tour groups, school trips, or family clusters by handling boarding passes and baggage drop in one go.

As Changi Airport’s flagship carrier, Singapore Airlines is the go-to choice for many travellers departing from Singapore. With multiple check-in options and dedicated terminals (T2 and T3), SQ offers one of the smoothest departure experiences. Here’s how to check in step by step:

SQ

Flying with SQ is usually seamless, thanks to a range of check-in options from mobile to FAST kiosks. Here’s how you can get through the process quickly and efficiently:

1. 48–1.5 hours before: Check in online via singaporeair.com or the SingaporeAir app. You can also activate Auto Check-in so your boarding pass is issued automatically at T-48h.
   
   

2. If you have bags: If applicable, use the FAST kiosks to print bag tags, then drop them at the Automated Bag Drop. Otherwise, head to the manned counters to check in your bags.
   
   

3. If you’re carry-on only: You can head straight to departure immigration with your digital boarding pass.
   
   

4. Counters & cut-offs: SQ counters and bag-drop close 55 min before departure. Aim to arrive at the airport at least 2–3h before your flight to allow time for check-in, immigration, and boarding.

Scoot

Scoot operates out of Terminal 1 at Changi, offering budget-friendly flights with multiple self-service options. Check-in tends to move fast if you prepare in advance. Here’s what to expect:

1. 48–1.5 hrs before: Complete online check-in at checkin.flyscoot.com if eligible. Travellers needing visa checks, extra assistance, or who booked special services should use the counters.
   
   

2. At Changi (T1):

• Kiosk check-in: Available from 18h–65 min before departure.

• Automated Bag Drop: Print and attach bag tags at kiosks, then use the bag drop during the same window (18h–65 min before departure).
  
  

3. Counters & cut-offs: Scoot counters open about 3h before departure and close 60 min prior. Plan to be at the airport at least 2h early.
   
   

4. Boarding: Gates close 15 min before departure. Once you’ve cleared immigration and security, head to the gate early to avoid missing your flight.

SingSaver’s take

The KrisFlyer UOB Credit Card remains a strong pick for true SIA Group loyalists and those who use travel-related spend frequently. With 3 mpd on Singapore Airlines, Scoot, KrisShop, Kris+, and Pelago, it provides top value there, and the fact that all miles go straight into your KrisFlyer account (no conversion) adds simplicity. 

The everyday bonus categories are still decent — dining, transport, online shopping, etc. — but the recent change reducing the bonus from 3 mpd to 2.4 mpd in those (unless you meet the minimum SIA Group spend) makes it less unbeatable for casual spenders. Be sure you can hit the S$1,000 annual SIA Group spend to unlock that boost; otherwise, the 1.2 mpd base rate on other spend is modest.

SingSaver’s take

The Citi PremierMiles Card remains a very strong pick for travellers who want miles that don't expire, lounge access, and solid earn rates abroad. With 2.2 Citi Miles per S$1 overseas spend and 1.2 mpd locally, it rewards both travel and everyday spend — though overseas transactions carry the usual 3.25% FCY fee. 

If you spend often overseas or in foreign currency, this card can give you excellent value. For those whose spend is mostly local, there are competing cards with higher domestic earn rates or better bonuses.

SingSaver’s take

The American Express Singapore Airlines KrisFlyer Credit Card suits travellers who carry out frequent SIA-Group purchases and value simplicity in earning miles. You get 2 KrisFlyer miles per S$1 when spending on Singapore Airlines, Scoot & KrisShop (and up to 2 mpd on Grab for capped monthly spend), while “everyday” spend earns 1.1 mpd. 

With an annual fee of S$179.85 (first year waived) and welcome/referral bonuses, the card delivers good value if your spend is aligned with its bonus categories. However, its earn rate outside those categories is modest, and benefits such as “travel inconvenience / accident” cover are helpful but shouldn’t be relied on as a full substitute for dedicated travel insurance. Overall, it’s strong for loyal SIA users, less compelling for those with mostly local or casual spend outside the bonus categories.

SingSaver’s take

The DBS Altitude Visa Signature Card remains a strong pick for travellers and those who spend a fair amount overseas. With rates of 2.2 miles per S$1 on foreign-currency spend and 1.3 miles per S$1 on local spend, plus bonus miles when you pay the annual fee, it provides decent returns. The “miles for life” feature (no expiry) and 2 complimentary Priority Pass lounge visits each year enhance its appeal for frequent flyers. 

Aside from overseas spend, the rewards are more modest. With the foreign transaction fee and the relatively high annual fee, you’ll want to use it enough to offset its costs. For those who mostly spend locally or don’t need the lounge perk, there might be better value cards elsewhere.

Deciding what time to reach Changi Airport depends on several factors, including whether your flight is international, whether you're travelling light or checking in luggage, and even the specific terminal you're departing from.

While the general recommendation is to arrive three hours before departure for international flights from Changi, those travelling with only carry-on baggage and familiar with the airport's layout may find that slightly less time is sufficient.

Conversely, passengers checking in bags, departing during peak hours, or those who prefer a relaxed pace with time for shopping and dining should consider arriving earlier to allow for potential queues and airport navigation.
