You've posted a request and got a response. What do these numbers mean?
Let's start with the classes:
FIRST | First class |
BUS | Business class |
ECO | Economy class |
ECO+ | Economy plus / Economy comfort |
NON-REV | Listed standby passengers |
Have a look at this example:
On this flight, FIRST class is fully booked. Eight seats are available in BUSINESS class, 3 in ECONOMY PLUS, and 58 in ECONOMY. One standby passenger is listed, and that can be anyone traveling non-rev.
The green bar on the left means your chances of getting on board are good.
If a class is overbooked, you'll see a red number with a minus sign in front of it:
This flight has no FIRST or ECONOMY COMFORT class. ECONOMY class is overbooked by 9, and 3 other standby passengers are listed. The bar on the left is red, because your chances of getting on board are low.
A response can also show how many standby passengers are listed in each class:
On this flight, all 7 standby passengers are listed in BUSINESS class.
