Hotel online bookings and “MFN” clauses: can online platforms demand the best deal?

&nbsp,1. What is an MFN clause?
&nbsp,
MFN clauses, which appear in vertical agreements between suppliers and distributors, generally consist of an undertaking by the supplier to offer the distributor a price or rate no higher than the lowest offered to other clients. In the hotel online booking sector, an MFN clause obligates the hotel to always give the platform with which it has signed the clause the best price for hotel online bookings, the highest number of available rooms (maximum capacity) and the most favourable room booking and cancellation conditions.
