Using TripCheck, airline employees flying stand-by can now easily determine which flights might be available to them. Simply enter the date and time of desired departure and select up to three airlines. TripCheck comes back with Passenger Seat Availability (PSA) for flights that match your details. It shows if your chances are Great, OK, Poor or if the flight is at capacity or oversold. You can then select which flight you'd like to take and select two backup flights. You can also create multiple itineraries and save them for later access. Contact information for flights is provided for checking in. Then you get email or cell phone updates from 24 hours to one hour before departure. It's that easy!

How do you get your data?

We obtain data from Sabre® global distribution system and we look at how many seats are still for sale on that flight. We then interpret that data, put into our complex formulas to determine the Passenger Seat Availability class for that flight.

What airlines do you provide the PSA’s for?

We provide PSA’s for over 130 airlines around the world. To see a complete list of all the airlines we have available, click here

I noticed you do not show AA flights at all. Why?

American Airlines has opted out of providing their seat information through the Sabre® system we use. We are working on a solution to this.

Why is there no seat availability information for Southwest Airlines (WN)?

Southwest Airlines has opted out of providing their seat information through the Sabre® system we use. However, we do show their flight and contact information, so you may contact them directly for seat availability.

Why can’t you show me the actual numbers for flight?


We do not have access to the exact numbers for a flight as the airlines guard that as proprietary information. The only information we can obtain is how many seats are still for sale on that flight.

Does your system take into account the number of Non Rev’s listed for a flight?

No it does not. We are unable to determine exactly how many Non Rev’s are listed or are checked in for a flight. The PSA category is based solely on the number of seats still available for sale for that flight.

What do the categories mean?

We would love to give you exact number of seats available for each flight but we are unable to obtain this from the airlines. Thru our complex formulas we are able to calculate a general Passenger Seat Availability class or PSA for each flight. One thing to remember it is never a guarantee to get on any flight, and the same time, it is possible to get on an oversold flight. However, the better the category, the better your chances are on getting on a flight.

Category Description
GREAT This flight is the best option. It has plenty of open seats and your best chance of getting on.
OK This flight is looking better for non reving. It has open seats, but could still be a problem if every passenger shows up and you are low on the standby list.
POOR This flight has a few open seats, but once again your odds are not that great unless you are on top of the standby list.
CAPACITY This flight is booked right at the airplanes capacity with revenue passengers. Your odds of getting on this flight are not great, but it is still possible if you are high on the standby list and maybe a couple revenue passengers miss the flight.
OVERSOLD Almost all airlines oversell flights to account for no shows. When we use this descriptive, the chances are very slim you will get on this flight.

What exactly are ZED fares? And what does Low, Medium or High mean?

ZED stands for Zonal Employee Discount. In short, it is an agreement between airlines that permits airline employees to travel on another carrier at a discounted rate. Specific agreements between airlines determine whether you have to pay the Low, Medium or High level ZED fare.

How do I find out the level of my ZED fare on a given flight?

The level of your ZED fare depends on arrangements between your airline and the airline you plan to fly on. Typically, you can find this information on your airlines’ company website.

After we find the flight we want to take, what should we do next?

First, you need to have your authorization from your airline to travel on that chosen airline. Then you should call your chosen airline at the number listed to the right of the flight on Tripcheck and list those traveling. ASU doesn't directly book flights through TripCheck. You have to list yourself as an authorized employee or dependent of your airline.

What do I do about return flights? How do I know the status of my flight after a certain period of time?

You can put in an itinerary for your return trip and if you have given us either your phone number or email, our system will notify you on your phone or inbox as to the status. You can also log back into ASU while on the trip from any computer connected to the internet and check your saved itineraries for up-to-date seat availability.
