Just days left to comment on Bristol Airport expansion plans People are being urged to make comments to be heard at the public inquiry ahead of a deadline of February 22 Updated Bristol Airport People have just a matter of days to make comments on plans for a major expansion at Bristol Airport - ahead of a public inquiry to decide its future. The inquiry to decide on the expansion plans is to open on July 20 and is scheduled to sit for 16 days. The airport appealed against a decision by North Somerset Council last year to reject its expansion plans which would see passenger numbers grow from 10 million to 12 million a year.
