Immigration Lines in Saigon and Da Nang

Hi all,

I'm going to Vietnam in July, flying into Saigon (Ho Chi Minh City) and then taking a domestic flight to Da Nang (tickets booked with same airline) is a 2 hour layover enough? (We will be taking the same flights back but of course in the opposite direction.) I heard the immigration lines are very long. I'm also worried as this will be the the first month of the health declarations coming into effect and it may cause delays while the airport navigates that.

For context there is two of us flying together, we both have EU passports and are flying from Perth. I have a Polish passport and therefore don't require a visa, my boyfriend has an Irish passport and has already got his tourist visa approved.

Any tips and tricks for our upcoming trip?

Thank you 😊
