Plans to double the size of Bristol Airport will go on public display on Wednesday.
The airport says the £80m scheme is to meet growing demand, but it has been criticised by environmental groups.
If approved, the plans mean a bigger terminal, more car parking and a new hotel to cope with an expected nine million passengers a year.
Campaigners are concerned about increased noise, pollution and traffic in the area.
The plans are available to view at North Somerset Council offices in Weston-super-Mare.
