Houston (CNN) - Just when you thought flying coach couldn't get more cramped, get ready for a tighter squeeze.
United Airlines has announced plans to install slimmer seats to fit more passengers.
Flying coach is rarely comfortable.
"Very uncomfortable and I was sitting up on row 10 and they still were small so I can't imagine them getting any smaller," said traveler Hazel Smith.
And for coach passengers on United Airlines it's going to get even more cramped. The airline says it's going to retrofit 152 of its planes with slim line seats, reducing the seat size from 18 inches to 17 inches.
The change will allow for six extra seats in the cabin. United says its passengers shouldn't notice the change, especially since leg room won't be affected.
The airline also plans to equip its entire fleet with WiFi capabilities by 2015, but Paul Sonnier says that's no consolation.
Man passengers realize space on an aircraft is becoming a rare commodity, and these latest changes will be made sometime next year.
Other major airlines have also announced plans to install slimmer seats to fit more passengers on board.
