1. Searching for Flights on Trip.com

The Trip.com flight search interface is clean but packed with features. Start by entering your departure city, destination, and dates. For round-trip searches, the return date field appears automatically. For one-way or multi-city trips, toggle the trip type at the top of the search box.

The "Passengers" dropdown lets you specify adults, children, and infants. Infant fares (under 2 years) are usually 10% of the adult fare and do not include a separate seat. Children (2 to 11 years) typically get a discounted fare with their own seat. Always enter the correct ages, as airlines verify this at check-in.

The "Cabin Class" selector offers Economy, Premium Economy, Business, and First. If you are flexible, search in Economy first to see the baseline price, then check Business Class. During sales, the premium cabin can be as little as 30% more than Economy and is often worth the upgrade on long-haul routes.

2. Reading Flight Search Results

After searching, Trip.com displays a list of flight options. Each result card contains a lot of information. Here is how to read it effectively.

  • Airline and Flight Number: The airline logo, name, and flight number are shown at the top. Click the flight number to see aircraft type and historical on-time performance.
  • Departure and Arrival Times: Local times are shown for both departure and arrival. Pay attention to the +1 or +2 indicators, which mean the flight arrives the next day or two days later due to time zones.
  • Duration and Stops: Total travel time and number of stops are displayed. For connecting flights, the layover duration and airport are shown. A layover under 90 minutes is tight at large airports; 2 to 4 hours is comfortable.
  • Price and Inclusions: The base fare is large and bold. Below it, Trip.com lists what is included: checked baggage allowance, carry-on limits, meal service, and seat selection. This is where low-cost and full-service airlines diverge significantly.
  • Refundable Badge: A green "Refundable" tag means the fare allows changes or cancellation according to the airline's policy. Non-refundable fares are usually marked "No Refund."

3. Selecting Seats and Add-Ons

After choosing a flight, Trip.com takes you to a page where you can select seats, add baggage, purchase travel insurance, and book airport transfers. Here is what to consider at each step.

Seat Selection

Most airlines charge for advance seat selection on Economy fares. Exit row and front-cabin seats cost more. If you do not select a seat, the airline assigns one at check-in, usually a middle seat toward the back. For couples or families, advance selection is highly recommended.

Baggage

The base fare includes a carry-on bag (usually 7kg). Checked baggage is either included (full-service airlines, typically 23kg) or must be purchased separately (low-cost carriers). Adding baggage during booking is cheaper than at the airport.

Travel Insurance

Trip.com offers travel insurance at checkout. Coverage includes trip cancellation, medical emergencies, and baggage loss. If your credit card already provides travel insurance, check the overlap before purchasing. Otherwise, the insurance is reasonably priced and worth it for international trips.

4. Passenger Details and Special Requests

The passenger details page is where accuracy matters most. Enter each passenger's name exactly as it appears on their passport or government-issued ID. Any discrepancy, even a missing middle name, can cause boarding issues.

For passport details, enter the passport number, nationality, date of birth, and expiration date. Some destinations require the passport to be valid for 6 months beyond the travel date. Trip.com warns you if the expiration is too close, but double-check the entry requirements for your destination country.

Special requests include meal preferences (vegetarian, halal, kosher, child meal), wheelchair assistance, and unaccompanied minor services. Submit these during booking, as airlines require advance notice for special meals and assistance.

5. Payment and Confirmation

Trip.com accepts credit cards (Visa, Mastercard, Amex, JCB), debit cards, PayPal, and select local payment methods depending on your region. The payment page is encrypted with SSL, and Trip.com does not store your full card details.

Before paying, review the total breakdown. It should include the base fare, taxes, fees, and any add-ons you selected (baggage, seat, insurance). If you have a promo code, there will be a field to enter it here. If you are a member, your Trip Coins balance is shown and can be applied as a discount.

After payment, you receive an e-ticket confirmation by email within minutes. This is not a physical ticket; it is your booking reference. You use it to check in online (usually 24 to 48 hours before departure) and to present at the airport if needed. Some airlines still require a printed boarding pass, but most accept mobile boarding passes now.

6. Managing Your Booking After Purchase

All your flight bookings appear in the "My Bookings" section of your Trip.com account. From here, you can view the itinerary, check in online, request changes, or cancel the booking.

Online check-in opens 24 to 48 hours before departure for most airlines. Trip.com provides a direct link to the airline's check-in page. Some airlines allow check-in through the Trip.com app itself, which is faster.

If you need to change dates or cancel, click "Manage Booking." The options available depend on your fare type. Flexible fares allow changes with a fee. Non-refundable fares cannot be changed, but in some cases, airlines allow you to pay a penalty and rebook. Trip.com handles the communication with the airline and updates your booking accordingly.

Quick Tips

Check in online as early as possible

Online check-in opens 24 to 48 hours before departure. Checking in early gives you better seat choices and reduces airport queue time.

Weigh your bags at home

Airport excess baggage fees are expensive. Weigh your luggage before leaving home to avoid surprises. Most airlines allow 23kg for checked bags and 7kg for carry-on.

Arrive at the airport early

For international flights, arrive 3 hours before departure. For domestic flights, 90 minutes is usually sufficient. During peak travel periods, add an extra 30 minutes.

Keep passport details handy

You may need to enter passport details during online check-in or at self-service kiosks. Have your passport accessible on your phone or in your carry-on.
