Just did EWR to LGA, on ETS. $30 each way, you end up getting an extra $140 or so for a trip start and stop in LGA as a EWR crew. Get the ETS shuttle at baggage claim in EWR at NJ Port Authority ground teams desk. Took 2 hrs because it went to JFK first. Not 24/7. EWR CP put out a blast mail about a 24/7 limo for $60.
