ANSWER · UK 261 AND EC 261
How close must the replacement flight be to avoid compensation?
Art. 5(1)(c) sets exact margins. With notice between two weeks and seven days, the replacement must depart no more than 2 hours before the original time and arrive less than 4 hours after it. With under seven days notice, the margins tighten to 1 hour early and 2 hours late. Miss either margin and compensation of €250, €400 or €600 or £220, £350 or £520 stays on the table.

The margins, exactly as the regulation sets them
| NOTICE GIVEN | REPLACEMENT MUST DEPART | AND ARRIVE |
|---|---|---|
| 14 days or more | Any time | Any time |
| Two weeks to seven days | No more than 2 hours early | Less than 4 hours late |
| Under seven days | No more than 1 hour early | Less than 2 hours late |
The half rate the airline can invoke instead
Where compensation is due but the reroute still landed reasonably close, Art. 7(2) lets the airline halve the payment: within 2 hours of schedule on flights up to 1,500 km, 3 hours on longer intra Community flights and others up to 3,500 km, and 4 hours beyond that.
