A Mexican airline, Volaris is offering one-dollar flights to undocumented migrants wishing to return to Costa Rica, El Salvador and Guatemala as the country struggles to curb arrivals from Central America.

The ‘Reuniting Families’ program announced by Volaris on Thursday aims to assist in the repatriation of migrants.

According to a statement on its Twitter account on Thursday, the airline said the offer will run until June 30 and is open to Central Americans in an irregular migration situations who wish to depart from airports in Tijuana, Ciudad Juarez, Guadalajara or Mexico City.

The statement stressed that interested passengers must also be willing to board the next available seat in order to take advantage of the ultra-cheap fare which does not include taxes.

It however added that adult migrants must identify themselves with their unique identity document while minors must show a passport or birth certificate.

A wave of Central American migrants have arrived in Mexico in recent months after the government of leftist Andres Manuel Lopez Obrador, who took office on December 1 declared that he would have a more flexible immigration policy.

However, the United States has registered record numbers of mostly Central American migrants crossing into the country illegally, sending tensions soaring between the two countries.

Following a threat by President Donald Trump to impose tariffs on Mexican imports, both governments reached an agreement which prompted Mexico to reinforce surveillance along its southern border as well step up the number of arrests and deportations of migrants.
