There are a number of different websites that provide information relating to vessel and aircraft estimated times of arrival.
The UK Public Transport Information link to external website website provides you with links covering all travel by rail, air, coach, bus, ferry, metro and tram within the UK, (including the Channel Islands, Isle of Man and Northern Ireland) and between the UK and Ireland. Plus all rail, ferry and coach travel between the UK and mainland Europe. This is the definitive index to timetables, fares, ticket-types, passenger facilities and lots more. If it's not here, it's probably not on the web.
