Emirates airline has unveiled plans to open up its lounges in Dubai to lower-tier frequent flyer members, said a report.

The moves comes as part of efforts to boost revenues after the airline reported a 75 percent drop in half-year profit in November, said a Reuters report in Emirates Business.

According to the new plan, the lowest of four membership categories, can pay $100 to access the airline's Dubai business lounge and $200 for the first class lounge.  

Moreover, Skywards members can now pay for access for non-member travel companions and upgrade from business to first class lounges, it said.

Will Horton, senior analyst at CAPA - Centre for Aviation, said there could be higher profit on lounge entrance fees than tickets given that it is rare for guests to consume food and beverages worth more than the fee.

Emirates, trying to counter the impact of overcapacity in the market and tighter corporate travel budgets, is looking at other additional revenue sources, including fees on bags. The airline also introduced fees for advanced seat selection for economy passengers in October.

Emirates also plans to introduce premium economy, a class between economy and business, by 2018, the report said.
