Does this show Air China award or upgrade availability?

No. The class filter here cannot reveal hidden award and upgrade classes. Use the Award and Upgrade Availability search instead.

Why does the same Air China flight show different availability in a connection than on its own?

Airlines manage inventory differently for connecting passengers and may reserve seats for through travellers. This is expected behaviour, not an error.

Does ExpertFlyer show Air China prices in cash or miles?

No. Flight Availability shows fare class inventory, meaning how many seats are for sale in each class, not prices. For fare amounts and rules, use Fare Information.

Why am I not seeing later Air China departures?

On busy routes not every flight can be returned in one query. Advance the Depart Time forward to page through later departures.

How to Use This Search

Use these fields to refine your search. Airline is prefilled for this carrier and can be changed.

Field	How It Works
Departing Airport	Enter the 3 letter airport code, for example SFO, or the first 3 letters of the airport or city name to see a matching list.
Arriving Airport	Same as above for your destination.
Depart Date	The date you want to travel.
Depart Time	The time of day to start results from. Busy city pairs have more flights than can be listed at once, so advance this time to page forward through the day.
Date Range	Expand the search to plus or minus 1, 2 or 3 days around your date. Premium subscribers only. Plus or minus 3 days is a hard limit.
Airline(s) (prefilled as CA)	Prefilled as CA on this page and editable. Up to 3 airlines can be searched.
Connecting Airport(s)	Specify up to 2 airports to filter for flights routing through those cities.
Exclude Codeshares (Air China)	Hides codeshare flights, showing only flights operated by Air China.
Only Show Class(es)	Enter up to 9 booking class codes to filter results to specific fare buckets. See the Air China class table below.
Connection Preference	Any, direct or non stop only, at least 1 connection, or at least 2 connections.
Point of Sale	Under Advanced Options. Some airlines show different availability by market. Default is USA; switching to UK can reveal different fare class availability.

Understanding the Results

Results show availability per fare class as a number next to a letter code. For example J4 means 4 seats available in full business class fare. A 0 means that fare class is sold out.

The number shown is the minimum number of seats available at that fare class. Sometimes more seats exist, but the GDS reports a capped number.

J44 seats available in full business class fare
Y0Economy full fare is sold out
Q33 seats available in discounted economy bucket Q
