We flew Aeromar from Guadalajara to Puerto Vallarta. I would highly recommend them. They fly small aircraft but they are fairly quiet and they serve a snack and a beer on the one hour flight. They were on time and the whole experience was very good. Puerto Vallarta was busier than Guadalajara with a mixture of domestic tourists and International ones.
We arrived around 6pm so we basically went to check in to the AirBnB and then walked into Zona romantica for dinner and had a stroll along the Malecon after dinner. Lots of people were out and about. There was some social distancing and mask wearing but it was certainly not 100%. There were less restrictions here than in Guadalajara. Restaurants did not have to close here however bars still needed to remain closed (any establishment that only serves alcohol)
The second day we did the hike up the the cross. It is as steep as I remember it but it affords great views. The weather was nice but it was a little cooler than usual for this time of year. On New Years Eve it actually dropped down to around 6 degrees. The daytime high was around 25 degrees.
6 degrees??? WOW. I miss PV so much. Glad you got to go there on your whirlwind Mexico tour!
