In 2026, travel technology has enabled flying between Los Angeles and Seoul to be quicker than it used to be, although some security measures have not been reduced. When you come across the letters SS SS on your paper when you are getting ready to fly to Trans-Pacific, it will imply that you have been selected to undergo Secondary Security Screening Selection. 

This is a normal practice that the Department of Homeland Security imposes on flights that are entering and leaving the United States. 

Giving a telephone call to the Korean Air Customer Support Phone Number Los Angeles is likely to make you comprehend how this influences your boarding procedure and check-in time.

Why you might see those four letters

The ssss code is not an error, it is an indicator that the Secure Flight system would like to take a closer examination of your travel profile with regards to this particular journey. On the occasions that it does occur, you cannot normally print your boarding pass at home or through a mobile version. There will be a need to visit an agent at the airport counter. 

Through Korean Air Phone Number Los Angeles, you could find out which area of the concourses you must visit first in order to get your physical paperwork being done by a staff member.

You were picked through random selection

Surprisingly enough, bad cases are the most prevalent reason to be flagged. The system is meant to select a given percentage of the travelers randomly so that the security process is not predictable. This is in order to ensure that all people are safe by ensuring that no one can determine who will be checked precisely. 

Probably, this is what happens to you, in case you are a frequent traveler and have never experienced a problem. You are just having your share of a few more minutes of attention.

Your ticket was a last-minute purchase

A flight to Asia can be very triggering an automatic flag in the system even when the reservation is made only a day or two before the flight. Algorithms used to guarantee security tend to perceive sudden and expensive international travel as an atypical trend relative to the normal vacation timing. 

In case you are in this situation, you can make a call to the airport phone number of  Los Angeles to confirm that your booking is complete. 

If you are traveling on a one-way 

Although one-way tickets are increasingly popular with digital nomads and long-term travelers, they still can help the cause of security in the whole world. The majority of travelers make round trip flights and thus a round trip flight to a far away place such as South Korea is memorable. In case you have an independent flight on another airline then inform the agent at the counter. .

Your name is similar to someone on a list

This is a very aggravating yet usual event to individuals who have very popular names. Assuming that your name is the same or close to that of a person on a government watch list, the system will require further verification in order to demonstrate that you are not that individual. 

In the long run, in case it occurs to you most of the time, you may want to inquire with the support team regarding application of a Redress Number. .

You paid for your flight with cash

Cash is regarded as extremely abnormal by security agencies in a digital payment era where transactions are made via credit card. When you visit a travel agency or a ticketing office and pay with physical currency, make sure that you will see the "SSSS" printed on your pass.

Your recent travel history looks unusual

In case you have just come back to the countries that the United States deems as high-risk or because you cross numerous stopovers on your way, the system might wish to confirm the aim of your travel. The security agents may question you on some basic issues like where you have been before or what you intend to do in Seoul. The most appropriate thing to do is to be candid and relaxed. 

The local support team in Los Angeles can help you to make sure that your itinerary is properly recorded into their system to provide help to the agents in the verification process.

You have an inconsistent booking pattern

Sometimes, bookings that were changed a few times or those that were last minute changed can make the system give it a second consideration. Travel itinerary stability is normally perceived as an indication of an ordinary traveler. 

In case something got out of control during your plans because of work or an emergency then a good number to call is the Korean Air Customer Support Phone Number Los Angeles and get your final itinerary fixed.

You have missed several previous flights

Sometimes by missing your boarding window more than a few times in a row, or just frequent no-shows, you may get a flag on your profile. The system searches through the patterns that are not a standard and sometimes booked but unutilized tickets may be a red flag. 

You don’t have to panic in case you have had a series of bad experiences with traffic or delays in the recent past. The secondary screening is simply a means by which the airport will check to make sure that all is fine before you are on your long journey across the ocean.
