...I wanted to pass this along and probably everone knows it.
Whenever we search for airfares we use "Number of seats - 1" even though there are two of us. If there is one seat left at a lower cost, Continental's system will not give it to you if you have specified that you want two seats.
Yesterday while searching, we found one seat available at $529.00 (plus tax), which we booked and choosing a seat with another seat free next to it. Then we immediately booked a second seat at $607.00 (plus tax), and selected the adjoining seat.
Making two reservations for one seat each instead of one reservation for two seats saved $78.00. It was worth the small effort.
Anyway, we are booked for 10 days! Hotel Millisime! Rue Jacob! Paris!!
