You will see there is a system map of the Elizabeth Line on page 1.

Citymapper is hardly the 'Ultimate Transport App' if it can't answer such a simple question.

I see my problem. My flight gets in at 5 A.M. but the Elizabeth line doesn’t start until 6:30 AM. 🤔
Thanks for your reply’s.

By the time you have cleared the border and collected your baggage it'll be 6.30 or close enough anyway.
You can't arrive in early on a 5am flight due to the night curfew at Heathrow.
Anyone who is doing business at the airport overnight, or has to arrive before the trains uses the N9 night bus straight to Trafalgar Square, or a whole network of night buses to the airport from surrounding areas, even Windsor and beyond. But there is no way you will get out of the airport before the last N9 leaves.
There are also night coaches to London Victoria from Heathrow on National Express.

Yes, our flights from SFO often would arrive early at LHR, but we have to wait to land because of the curfew.

btw I took the Elizabeth line to LHR last week. So nice. We usually take the Piccadilly line, which is fine, but has so many stops and takes longer.

The Elizabeth line even on a Sunday has a first service from Heathrow before 0600. Unless the dreaded engineering work is on.

Travelling from Wales (Neath) by train to Heathrow, I used to take the bus from Reading to Heathrow - and was never sure whether to pay for it separately or as an addition to my rail ticket.
But now the new Elizabeth Line seems to offer an alternative, though it seems one has to change at West Drayton. How does that compare with the bus link in terms of both cost and time taken? Has anyone here done that journey recently?

Change at Hayes and Harlington, rather than West Drayton.

In time terms probably about even, depending which terminal you want.

In cost terms train wins out, as due to a quirk in the fares system, London is cheaper than Reading from South Wales.

Advance to Reading is £34, then add the coach, whereas to Heathrow by train throughout is £36.60, but to Hayes and H is only £29.50, you could then hop a bus into Heathrow for less than £2. So on cost terms the Elizabeth line wins out over Coach.
If you think the coach from Reading or a 2 train option is the more convenient is a matter of personal opinion- I fall on the train option, others on the coach.
I don't think you can now book the Rail link coach with a train ticket- you did used to be able to, but doesn't seem to be a way to do so now.

If you are doing it as a return journey, the coach will is only £8 more than for a single which can tip the cost aspect.

My thanks to all for their replies. This will be a one-way journey (Neath to T2) at the end of my holiday; I get to Wales by train, Paddington to Neath. Actually from Granthm via King's Cross: I seem to recall that it is possible to buy a through ticket which covers the Underground fare from King's Cross to Paddington, but can't recall how that is done.

Hopping on a bus at an unfamiliar station is not so easy with luggage and a strained back, unless you know exactly which bus you want and where to catch it. So I'll probably opt for the familiar coach fom Reading, after all.

On the LNER website booking engine just put in Grantham to Neath.

Any fare you see will say 2 changes- on and off the Underground, and all those fares include the tube, as does any cross London through fare.

I've just randomly looked at 27 April- quite a few trains at £68, one at £60. Both those fares are cheaper than if you booked in 3 parts- Grantham- KC, Tube and Pad- Neath.

Thankyou @ isn31c - that's very helpful and good to know. Just waiting now for the tour company to confirm the time I'll be able to leave Grantham, as they provide transport to that station.
