Well Thailand is desperate for tourist income but the situation is still not good. Arrivals are still required to quarantine for 7 days even if they have been vaccinated. In addition foreigners must pay for their own covid testing which is over 8000 baht. So even though Thai airways has flights to Bangkok from Europe and North America, the situation is not good for tourists.
Within Thailand itself there are restrictions on movement between provinces. So the usual flow between the provinces and Pattaya is not possible reducing the available labor pool. Remember that over 11,000 daily cases are recorded.
