United Airlines is telling its corporate and
agency customers to be prepared for the sale of Basic Economy fares by Feb. 21
for travel dates beginning in mid-April. The carrier said the fares at first would
be available in select U.S. markets and for short-haul flights to the Caribbean
and Latin America. The fare, designed to compete with low-cost carriers, comes
with several restrictions, including no seat selection, no flight changes and a
carry-on limit to a single personal item.
