If you mean at Oceanside, then yes. You will need a credit card.

The Coaster is running a modified schedule: no weekend service and about 1/2 of the daily rips are suspended. Face masks are required on their trains. The website has the following information (and much more). This info is from the gonctd website: North County Transit District (NCTD) is experiencing significant declines in ridership and has determined that temporary service reductions will be implemented for COASTER commuter trains.

Please read the following from their website and also keep in mind that disabled passengers pay the same fare as senior citizens (half price). Here is the info regarding the modifications: All COASTER stations provide ADA-compliant level boarding through the use of bridge plates. Stations typically provide accessible ticket vending machines, public address systems, information displays, and accessible parking. Every station has a walkway or a ramp from the street level to the boarding platforms. Truncated domes on all platform edges alert passengers to take care when approaching the edge of the platform.

I think you would have to take the Coaster to the Santa Fe Depot in downtown San Diego. From there catch Lyft or Uber to the San Diego Airport.

You take a bus. Short ride. Cheap. Or an Uber. Its all in tbe websites. Both Coaster and bus websites and airport.

Yes, get off @ Old Town & take #9 MTS Bus to SeaWorld

First, I hope you are going to San Diego, From Carlsbad village go to the end of the line in San Diego, and take the bus to the airport. Not sure which one, but I know it runs every 15 min.

Take the 992 bus from outside arrivals and get off at Santa Fe. The stops are announced on the bus. Check Coaster times as there are none after 7-13pm other than on a Friday night when the last 2 are 8-12pm & 11-15pm. if the Padres are playing at Petco there is a Coaster that departs 1 hour after the end of their game . Best check NCTD website for the schedule & any cancellations etc.

well first, the coaster doesn't get to the SD airport but the nearest station is SD Old Town. From there you have to get a cab or a uber to go to the airport (10 mins ride). I guess you can find timetable for Carlsbad to SD Old town on the Web.
