Loveholidays has followed On the Beach in resigning its Abta membership.
The OTA has cited "divergent views" on its and Abta’s stance on the legal position around cancellations and refunds.
It comes just two days after fellow OTA, On the Beach, resigned its Abta membership over similar concerns.
"The Covid-19 pandemic has caused unprecedented challenges for holidaymakers, which have been exacerbated by frequent changes in travel guidance issued by the UK government," said a loveholidays spokesperson.
"The current package travel legislation was never designed to deal with disruption on the scale we have seen since March 2020. Unfortunately, as a result of our divergent views on the legal position regarding cancellations and refunds, we have decided that it is no longer possible for loveholidays to remain a member of Abta."
