I want to go back from this hotel to catch my flight of 10:00AM on saturday morning. so can anyone guide me with proper route, transport and what time should i checkout.

Thanks for all the help till now!

There is a joke about the police getting called when someone tried to pay with a $2 bill http://www.snopes.com/business/money/tacobell.asp . This has actually happened to me though. There is loads of fun to be had with $2 bills if you have some time to kill

BART train, the Bay Area Rapid Transit, will be the cheapest and most convenient.

It appears that your hotel is near the MacArthur station. There is a direct train from there to SFO airport, takes about an hour. If you leave your hotel at about 6:30 you should be fine for a 10:00 flight. Check with your hotel front desk about advise on getting to the BART station.

This on the other hand is excellent advice. BART is the fastest and cheapest way from Oakland to SFO, the fare is $8.60, and you can pay with a credit card. See www.bart.gov for schedules.

I am a long time 1k and million miler and I've been "not helped" by United so many times that I have lost track.

Also, if his two flights happen not to be on the same record, there are United agents out there who will try to collect penalty charges.

It's good that you have had better experience, and I hope for the same for the OP who, for all we know, is Global Services member -- the only category of United customer who can reliably count on assistance.

I am not implying that United is necessarily any worse than any of the other large domestic carriers in this regard. All too often, particularly on domestic flights, being treated as human rather than as "self-loading cargo" is, unfortunately, an unrealistic expectation.

This is the most cost-effective way. But at the risk of being again accused of upsetting the OP unduly, I note that there could be a BART strike starting as soon as October 11.

No, I've had terrible experiences with UA, especially since March 2012, and I hate them as much as the next guy. I try to avoid them noawadays. But if your flights are on a single PNR and you misconnect owing to their own operational problems, they will rebook you, not attack or ignore you. You might have to stand in a line and endure rude personnel but you will get on your way. The OP is worried enough about his trip that we shouldn't be creating new unnecessary fears.

One more question is:

I am going to take hair oil, but i am having only carry on bag for me. Now the thing is i have a plastic bag as listed in tsa website but can i take small sachet or pouch of hair oil or it is compulsary to take them in the 100ml bottle?

Any other tips, should i show that bag separately ?

It is not illegal to do so, and in practice won't cause any problems. Some overseas moneychangers do this so that they can identify the specific bills that they gave you should you bring them back for some reason. One reason might be if you somehow get stuck with a counterfeit $100 bill and try to make a claim with the moneychanger - by looking for their stamp, they can tell if the bad bill is one that they gave you, or one you got somewhere else and are trying to get them to refund anyway. Another reason is that some moneychangers offer you a deal whereby you can turn in unused foreign currency once you get back from your trip and they'll give you back your original money, including the service fees / exchange rate. To do this, they need to know that you're returning the bills they actually gave you, and not some others you got elsewhere.

Can someone reply me here, its quite urgent?

Anyone, reply!

I understand what you are asking. According to the TSA website, it states bottles. Not sure how much leeway they will give you.

thanks all, i made it easily and enjoying myself. now the only question i have left is...how to go about returning from sfo to new delhi. at sfo airport do i need to take international or domestic rrival since it is sfo-ewr-delhi, and what to go at ewr..from departing from delhi i got the boarding pass for both flights, will it be the same case from sfo? what things do i have to clear here and go abut. can someone tell me step by step. where to get baggage etc .and do i need to reclaim the baggage and go through security lines at ewr again?.thanks a lot.

Dude, calm down! Breathe.

You'll check in for your flight at the terminal of the airline that you are flying from SFO-EWR. Assuming it's all on one ticket, you'll get boarding passes for both flights and your bags will be checked through all the way to Delhi. When you arrive in Newark, figure out what gate your next flight is leaving from and go there.

Are u sure..about baggage claim..it happened by chance when i was coming i had to reckaim it in newark first and then go to sfo...
