Be coming to thailand in may 2026 travelling with friends. We come home before them and thinking of upgrading to business class when returning from Bangkok to Glasgow via Emirates. Few questions regarding this.
Whats the best process for upgrading would it be via app, email or at the desk.
Would we need to do 2 seperate upgrades and if so has anyone did this and what would the total cost be per person for business class upgrade both legs via dubai.

Thanks in advance for any info
