i will commutin regularly... i can also go from feltham, jus wanna know which side will be easier, quicker and cheaper?
Easier is subjective. Different people will have different views on what is easier. Quicker is probably to minimise bus travel (or even eliminate it). Cheaper is probably to maximise bus travel and only take the train from Feltham. Your options are:
1: Season from Egham to Feltham and a bus season ticket.
2: Season from Egham to Travelcard zone 3. This would allow you to travel between Egham and Feltham and then anywhere within zones 3 to 6. You could get the bus from Ealing to Richmond or you could get the tube as mentioned by Oracle. Note that you don't need zone 2 for the journeys you are making, but the day travelcards aren't as flexible as travelcard seasons.
I wonder if taking the District Ealing Broadway > Turnham Green > Richmond then SWT to Egham is faster than taking the 65 down to Richmond?
Is there an option of a season from Boundary Zone 6 - Egham as well as obviously a Feltham - Egham one?
Boundary tickets are single or return journey extensions. Seasons can be bought for unlimited travel between a station outside the zones and the travelcard boundary then anywhere within the zones attached. The cheapest option includes zones 5 and 6 rising up to one including all 6 zones. Obviously there are also options in the north west including zones 7 8 and 9, but that is complicating the issue on this thread somewhat.
