Shown above is the basic entry to book a segment from an availability display. It is also the entry to waitlist a segment from an availability display. It is used to waitlist a sold-out flight in an existing flight availability display.

Recall that an Alpha Availability display shows an "L" after the booking code when a flight is sold out and can be waitlisted, and a Numeric Availability display shows a "0" or an "L". When you see either an "L" or a "0" in an availability display, the sell entry will automatically waitlist the flight.

The basic sell entry shown will place one booking code Jseat from the flight on line 2 of an existing availability display on the waiting list.
