Many airlines are now offering free or cheap companion tickets.

Northwest currently has certificates which will allow a companion to
fly at a reduced price ($199 round trip between the east and west coast,
cheaper between shorter hauls).  Travel must be completed by 1/15/94,
Saturday night stay is required, and there are a lot of holiday period
blackout dates.  Companion earns frequent flier miles.

Continental offers a deal to their One pass members where for $50
you can get a package which includes 5000 miles and a $99 RT companion
ticket certificate.  There may be some blackout dates on the certificate,
but I was able to use this around Christmas time.  Companion earns
frquent flier miles.

TWA is currently offering promotions by which it is possible to fly with
them and get a free companion ticket certificate valid some months in 1994.
