Joining Your Tour & Airline Information (Southeast Asia)

Check-in information

With most airlines, you can check in online 24 hours prior to departure. Make sure you have your passport information and airline reference number handy. Your airline reference number is 6 letters or digits long and can be found on your e-ticket receipt.

You are able to manage your booking and select your seats online through your airline's "manage my booking" section. Please note that some airlines will allow you to pre-book seats more than 24 hours in advance but will usually charge a fee to do this, which needs to be paid to the airline directly by phone or via their website. Please refer to your airline’s website for further information.

We recommend you arrive at the airport at least 3 hours prior to your international departure, even if you have checked in online, to make sure you clear security in good time.

If you do not have access to the internet, we again recommend that you arrive at the airport 3 hours prior to departure where you can either use one of the available check-in desks or the self-service kiosks before taking your luggage to the bag-drop area.

Baggage information

We recommend that you do not exceed 20kgs of checked in baggage on your international flights as many of the domestic airlines within Southeast Asia have a luggage allowance of only 20kgs. As a guide, your main baggage should not exceed the following dimensions: 90cm x 75cm x 43cm (35.5ins x 29.5ins x 16ins), including the handle, pockets and wheels, and your cabin baggage should not exceed 55cm x 40cm x 20cm (22ins x 16in x 8ins), maximum weight 5kgs. For further information please refer to your airline’s website.

If your tour involves a lot of train travel, we would recommend packing as lightly as possible. Porterage is not included in Southeast Asia and you will need to be able to carry your own luggage.

Terminal information

This is shown on your e-ticket.

Transit information 

If you are transiting from a domestic flight to an international flight (such as domestic flight Melbourne to Sydney, then international flight Sydney to Saigon), or vice versa, you will need to go through immigration during your stopover, collect your luggage, change terminals and re-check in your luggage for your next flight. Allow plenty of time to complete airport formalities. If you're unsure if this applies to you, check with the airline counter before your first flight. 

If you are transiting from one international flight to another international flight (such as in Singapore or Hong Kong), your luggage will be checked all the way through to your onward destination. You do not need to go through immigration or collect luggage. You may need to change terminals, refer to your boarding pass and information screens at the airport. 

If you miss your connection, please immediately speak to the airline counter to organise a new flight. Wendy Wu Tours is generally unable to assist you with missed connections as the airline has control of your flights. Please refer to your final itinerary document for contact information if your flight into your arrival destination changes.

Tet Nguyen-Dan or ‘Tet’ is the Vietnamese New Year celebration, which lasts for three days in late January or early February. However, in reality, the celebrations go for up to ten days. During the Tet holiday, all businesses are closed and work in Vietnam slows down. Please expect tourist sites to be busier than usual. New Year celebrations for Cambodia, Laos and Thailand are in mid-April every year.
