In general, February is the cheapest month to fly from United Kingdom to Rosario. Due to it being the ‘off-season’ during this time, you can expect flight prices to be around £636. If you aren’t able to travel during the month of February, then book flights to Rosario from United Kingdom during June instead. Flights to Rosario in June, while not as cheap as those in February, still average around £778.
Currently, Argentina travel restrictions include travel to Rosario. Argentina has restricted entry to all travelers except for citizens and residents until at least June 7, 2020. Airlines operating repatriation flights must send all passenger information to ANAC 12 hours before departure. This information must contain the passenger list with travel document numbers, phone numbers, and addresses where each person declares that they will comply with the mandatory quarantine upon arrival. If you are planning to travel to Rosario at this time, it is recommended that you stay up to date on current restrictions and follow proper safety measures while in public.
