Flying Jan 17 on AA1946 (SAN-DFW). Schedule allows us, in wheelchair transport, 1 hr 20 minutes (including taxiing and deboarding and getting on the next flight) to get to AA0937 to Rio de Janeiro. Is that a reasonable time? Will be in business/first. I might be able to pay cruise line for change to earlier flight out of SAN, if appropriate. Do the wheelchairs go on the train along with the pusher?
