If you are there UNTIL Friday... you are THERE Monday, Tuesday, Wednesday, Thursday, but leaving Friday morning probably. If you are going to be there BY Friday then you are ARRIVING sometime that week, perhaps Wednesday or Thursday. Certainly by Friday you will be there. They are almost OPPOSITES of each other. You put money INTO/IN your bank/bank account. A bank is a bit like a BOX you can put things IN. You can put money ON/ONTO your phone card/cashcard - it's not easy to put it IN a card, but you can put things ON it. Does it help to think of it this way?????

Using until in that sentence means that you are in the location and that you will leave on Friday. Using by in that sentence changes the meaning to you not being in the location, but you will arrive no later than Friday.
