Travellers — their reservations well in advance if they want to fly during the Eid holidays.

✅ কেন সঠিক: ‘Had better’ is followed by the base form of the verb without ‘to’: Travellers had better get their reservations early.

❌ অন্য অপশন: ‘had better to get’ adds a wrong ‘to’; ‘had better got’ uses a past form; ‘had to get better’ changes the meaning.

💡 মনে রাখুন: had better + V1 (no ‘to’) = should, as advice or warning: You had better leave now.
